FAQs
My deck boards are starting to warp and splinter. Can you repair just the damaged sections, or do I need a full replacement?
If the joists and structural framing are still sound, we can remove and replace only the damaged deck boards or composite planks. We’ll match the material type, color, and spacing to keep the deck uniform. A full replacement is recommended if the substructure has rot, widespread cracking, or if the deck is more than 15–20 years old and no longer meets current Seattle building codes.
One of my fence gate latches keeps slipping open. What’s causing this and how do you fix it?
In Seattle’s wet climate, wooden gate posts can shift as the soil expands and contracts, pulling the latch out of alignment. We inspect the post stability first—sometimes a leaning post needs re-bracing or a concrete footing reset. Then we replace rusted latch hardware with a marine-grade stainless steel model and adjust the strike plate so the gate closes squarely.
I want to add a second-story addition to my bungalow. Do you provide the structural design as part of your service?
Yes, we offer in-house construction design services for building additions. That means we can take your project from concept through permitting and construction. For a second-story addition, we coordinate with a structural engineer to ensure the existing foundation and walls can support the new load, and we handle all zoning and setback requirements with the Seattle Department of Construction and Inspections.
