Gutters are easy to ignore until they cause problems. But these simple channels play a critical role in protecting your home. When gutters work properly, they direct thousands of gallons of rainwater safely away from your foundation, walls, and landscaping. When they fail, water goes where it shouldn't, causing damage that's expensive to repair.
Hawaii's climate makes gutter maintenance especially important. Heavy tropical rains can overwhelm clogged gutters in minutes. Trade winds deposit leaves, seeds, and debris year-round. And our lush vegetation means there's always something falling onto your roof and into your gutters.
Foundation Protection: Your gutters' primary job is keeping water away from your foundation. When gutters overflow, water pools around your home's base, saturating soil and potentially causing foundation movement, cracking, or water intrusion into basements and crawl spaces.
Fascia and Soffit Protection: Clogged gutters hold standing water against your fascia boards and soffits. This constant moisture causes rot, paint failure, and wood deterioration. Replacing rotted fascia is far more expensive than cleaning gutters.
Landscape Protection: Overflowing gutters dump concentrated water streams onto landscaping, causing erosion, plant damage, and soil displacement. Properly functioning gutters distribute water to appropriate drainage areas.
Roof Protection: When gutters clog, water can back up under roofing materials, causing leaks and deck rot. In severe cases, the weight of debris and standing water can pull gutters away from the house, damaging the roof edge.
Pest Prevention: Standing water in gutters creates breeding habitat for mosquitoes. Decomposing debris attracts insects and can provide nesting material for birds and rodents. Clean gutters eliminate these pest attractions.
Thorough gutter cleaning goes beyond scooping out visible debris. Here's what our service includes:
We remove all debris from your gutters by hand, including leaves, twigs, seeds, dirt buildup, and any other material that's accumulated. We don't just clear a channel through the debris; we remove everything down to the gutter bottom.
Roof Debris: We also clear debris from the roof areas immediately surrounding gutters. Leaves and debris on your roof will wash into clean gutters with the next rain, so clearing these areas extends the benefit of cleaning.
Gutter Guards: If you have gutter guards installed, we work with them appropriately. Some guards need to be removed for proper cleaning underneath; others can be cleaned in place. We handle all guard types.
Clogged downspouts are a common problem that homeowners often miss. Gutters can appear clean while downspouts are completely blocked. We flush all downspouts with water to verify they're clear and flowing properly.
Clog Removal: If downspouts are clogged, we clear them using appropriate methods. Most clogs can be cleared with water pressure or manual snaking. Severely impacted downspouts may require disassembly.
Underground Drains: If your downspouts connect to underground drainage, we verify water is flowing into these systems. Blocked underground drains cause the same problems as clogged gutters.
While cleaning, we inspect your entire gutter system for problems:
Sagging Sections: Gutters that have pulled away from the fascia or sag between hangers don't drain properly. We identify sections needing reattachment or additional support.
Leaking Joints: Seams and joints can separate or develop leaks over time. We note any joints that need sealing.
Rust and Corrosion: Metal gutters can rust, especially at seams and in areas where debris collects. We identify corrosion that may require repair or section replacement.
Proper Slope: Gutters must slope toward downspouts to drain completely. Sections that have shifted or weren't properly installed may hold standing water. We identify slope problems.
Hanger Condition: Gutter hangers can bend, break, or pull loose. We check hanger condition and spacing throughout the system.
Fascia Condition: We inspect the fascia boards behind your gutters for rot, damage, or paint failure that may indicate moisture problems.
After cleaning and inspection, we flush the entire system with water. This final test verifies gutters are draining properly, downspouts are clear, and water is flowing away from your foundation as intended.
When cleaning reveals problems, we provide repair services to restore proper function:
Sagging gutters don't drain properly and can eventually pull away from your house entirely. We repair sagging sections by:
Hanger Replacement: Bent, broken, or missing hangers are replaced with appropriate hardware. We use hangers rated for Hawaii's rainfall intensity.
Additional Support: If hangers are spaced too far apart, we add additional hangers to provide proper support. Heavy tropical rains require adequate support to prevent sagging under water load.
Fascia Repair: If fascia boards have rotted and can't hold hangers, we repair or replace damaged fascia sections before reattaching gutters.
Realignment: We realign sagging sections to restore proper slope toward downspouts.
Leaking gutters defeat their purpose and can cause the same damage as no gutters at all. We repair leaks at:
Seams and Joints: Where gutter sections connect, seams can separate or sealant can fail. We clean, prep, and reseal leaking joints with appropriate gutter sealant.
End Caps: End caps can loosen or their seals can fail. We resecure and reseal end caps as needed.
Corners: Inside and outside corners are common leak points. We address corner leaks with proper sealing techniques.
Holes and Rust-Through: Small holes can be patched. Larger damaged areas may require section replacement.
Downspouts take abuse from ladders, yard equipment, and general wear. We repair:
Loose Connections: Downspout sections that have separated are reconnected and secured.
Damaged Sections: Crushed or damaged downspout sections are replaced.
Elbows and Extensions: Damaged elbows and extensions that direct water away from the foundation are repaired or replaced.
Straps and Brackets: Loose downspouts are resecured to the wall with appropriate hardware.
When damage is too extensive for repair, we replace gutter sections:
Matching Materials: We match new sections to your existing gutters in material, size, and color when possible.
Proper Integration: New sections are properly connected to existing gutters with sealed joints.
Full Sections: Sometimes replacing a full run is more economical and effective than patching multiple problems in deteriorated gutters.
Tired of cleaning gutters multiple times a year? Gutter guards reduce debris accumulation and cleaning frequency:
Mesh Guards: Fine mesh screens allow water through while blocking leaves and debris. Effective against most debris types but may require occasional surface cleaning.
Solid Covers: Solid guards with a curved edge use surface tension to direct water into the gutter while debris slides off. Work well for leaves but may struggle with heavy Hawaii rainfall.
Foam Inserts: Foam blocks that fit inside gutters, allowing water through while blocking debris. Less expensive but may degrade faster in Hawaii's UV-intense environment.
Brush Guards: Cylindrical brushes that sit in gutters, allowing water flow while catching debris on top. Easy to install but require periodic removal for cleaning.
Hawaii's conditions affect gutter guard performance:
Heavy Rainfall: Guards must handle intense tropical downpours without water overshooting the gutter. Some designs that work on the mainland can't keep up with Hawaii rain intensity.
Fine Debris: Hawaii has many trees and plants that drop small seeds, flowers, and fine debris. Guards that block leaves may still allow fine material through.
UV Exposure: Plastic and foam guards degrade in Hawaii's intense sun. Metal mesh guards typically last longer.
Our Recommendation: We assess your specific situation, including surrounding vegetation, roof type, and gutter configuration, before recommending guard options. No single guard type is best for every situation.
Oahu presents specific challenges for gutter systems:
Hawaii's tropical rains are intense. A heavy downpour can drop inches of rain in minutes, overwhelming undersized or clogged gutters almost instantly. Gutters that handle mainland rainfall adequately may be undersized for Hawaii conditions.
Gutter Sizing: Standard 5-inch gutters handle most residential applications, but homes with large roof areas or in high-rainfall zones may benefit from 6-inch gutters. Downspout sizing and quantity also affect capacity.
Unlike mainland locations with distinct seasons, Hawaii's vegetation drops debris year-round. There's no "after the leaves fall" cleaning that handles a whole year. Mango trees drop leaves and fruit. Palms drop fronds and seeds. Monkeypod trees drop flowers and seed pods. The debris never really stops.
Cleaning Frequency: Most Hawaii homes benefit from gutter cleaning at least twice yearly. Homes with significant tree coverage may need quarterly cleaning.
Conditions vary significantly across Oahu:
Windward Side: Kaneohe, Kailua, and the Windward coast receive more rainfall and have lusher vegetation. Gutters here work harder and may clog faster.
Leeward Side: Ewa Beach, Kapolei, and West Oahu are drier but still experience significant rain during Kona weather. Dust and fine debris may be more of an issue than heavy leaf fall.
North Shore: Winter storms bring heavy rainfall and winds that deposit debris. North Shore gutters face seasonal intensity.
Coastal properties face accelerated corrosion from salt air. Metal gutters, especially steel, rust faster near the ocean. Aluminum gutters resist corrosion better and are often the better choice for coastal Hawaii homes.
We provide gutter services across the entire island:
Mililani and Central Oahu: Central Oahu homes often have mature landscaping with significant tree coverage. Regular gutter cleaning keeps systems functioning despite year-round debris from monkeypod, mango, and other common trees.
Ewa Beach and Kapolei: West Oahu's newer developments often have younger landscaping, but gutters still accumulate debris and require maintenance. We serve Ewa Beach and Kapolei homeowners with cleaning and repair services.
North Shore (Haleiwa, Kahuku, Laie): North Shore properties face heavy winter rainfall and salt air exposure. We help North Shore homeowners maintain gutters that handle seasonal demands.
Kaneohe and Kailua: The Windward coast's heavy rainfall makes gutter function critical. Clogged gutters here cause problems faster than in drier areas. We prioritize proper drainage for Kaneohe and Kailua homes.
Waianae Coast: Coastal exposure means corrosion concerns. We inspect for rust and recommend appropriate materials for Waianae gutter repairs and replacements.
Honolulu and Hawaii Kai: From urban Honolulu to coastal Hawaii Kai, we provide gutter services throughout the metro area. Varied conditions across neighborhoods require individualized assessment.
Sometimes gutter problems are symptoms of roof issues:
Granules in Gutters: Excessive roofing granules in gutters indicate shingle wear. Some granule loss is normal, but heavy accumulation suggests your roof may be approaching end of life.
Fascia Rot: Rotted fascia behind gutters often results from roof leaks or ice dam effects (rare in Hawaii but possible at elevation). We assess whether fascia damage indicates underlying roof problems.
Water Behind Gutters: If water is getting behind your gutters rather than into them, the drip edge or roof-to-gutter interface may need attention.
Integrated Assessment: Because we handle both roofing and gutters, we can identify when gutter problems point to roof issues and recommend comprehensive solutions.
We're not just a gutter cleaning service. We're your local partner for complete home water management:
Thorough Service: We don't just scoop and go. Our cleaning includes debris removal, downspout flushing, system inspection, and final testing. You know your gutters are actually working when we're done.
Repair Capability: When cleaning reveals problems, we can fix them. No need to schedule another contractor for repairs we identify during cleaning.
Licensed Contractors for Larger Jobs: Hawaii law currently requires a contractor's license for work exceeding $1,500. For gutter repairs or replacements that exceed this handyman limit, we have licensed contractors in our network to handle the job properly and legally. If House Bill 442 passes, this threshold will increase to $2,500, but regardless of where the limit stands, we ensure your work is done by appropriately licensed professionals when required.
Roof Integration: We understand how gutters relate to your roof system. We can identify roof issues that affect gutters and gutter issues that affect roofs.
Hawaii Expertise: We know which gutter configurations work best for Hawaii's rainfall, which materials resist our salt air, and how local vegetation affects maintenance needs.
Honest Assessment: We tell you what your gutters actually need. If cleaning is sufficient, we say so. If repairs are needed, we explain why. If your gutters need replacement, we'll discuss options rather than pushing unnecessary work.
How often should I have my gutters cleaned?
Most Hawaii homes benefit from gutter cleaning at least twice a year. Homes with heavy tree coverage, especially mango, monkeypod, or palms, may need quarterly cleaning. We can assess your property and recommend an appropriate schedule based on your specific conditions.
How much does gutter cleaning cost?
Basic gutter cleaning for typical single-story homes runs $150 to $250. Two-story homes typically cost $200 to $350. Larger homes, difficult access, or heavy debris accumulation may cost more. We provide quotes based on your specific situation.
How do I know if my gutters need repair vs. replacement?
Localized problems like a sagging section, leaking joint, or damaged downspout are worth repairing. If gutters have widespread rust, multiple failing sections, or are undersized for Hawaii rainfall, replacement may make more sense. We assess your system and explain your options honestly.
Are gutter guards worth it in Hawaii?
Guards can reduce cleaning frequency but rarely eliminate it entirely. Hawaii's fine debris, intense rainfall, and varied vegetation make guard selection important. We can recommend guards suited to your specific conditions, but we're honest that no guard is maintenance-free in Hawaii.
What type of gutters are best for Hawaii?
Aluminum gutters offer the best balance of cost, durability, and corrosion resistance for Hawaii conditions. For coastal properties with severe salt exposure, aluminum is strongly preferred over steel. Seamless aluminum gutters minimize leak potential and are our most common recommendation.
Can clogged gutters really damage my foundation?
Yes. When gutters overflow, water concentrates at your foundation instead of being directed away. This can cause soil erosion, foundation settling, basement moisture, and even structural movement over time. Proper gutter function is genuine foundation protection.
My gutters overflow even when they're clean. What's wrong?
Several possibilities: gutters may be undersized for Hawaii's heavy rainfall, downspouts may be too few or too small, slope may be incorrect, or heavy roof runoff may be overshooting the gutter. We diagnose the actual cause and recommend appropriate solutions.
Do you clean gutters on multi-story buildings?
Yes, we clean gutters on residential buildings of all heights with appropriate safety equipment. Very tall or complex buildings may require special equipment that affects pricing.
What if I see my gutters sagging after heavy rain?
Sagging during rain suggests inadequate support for the water load. This needs attention before gutters pull away from your house entirely. We can add hangers, reinforce supports, and restore proper slope.
Can you install new gutters if mine need replacement?
Yes. If your gutters are beyond repair or inadequate for your needs, we can install new seamless aluminum gutters sized appropriately for Hawaii conditions.
Do you offer maintenance plans?
We can schedule regular cleaning visits to keep your gutters functioning year-round. Maintenance plans ensure your gutters are cleaned on schedule without you having to remember to call.
What if my downspouts drain into underground pipes?
We verify water is flowing into underground drainage systems. If underground drains are clogged, the problem may be beyond typical gutter service, but we can identify the issue and recommend next steps.
