It went extremely well and I would not hesitate to hire these guys again. The project took longer than they expected but they kept going and always delivered high quality work and never cut corners. They also worked directly with a neighbor on the wall between our properties and made sure...

Great work, took off three layers of old roofing. Installation was some of the best work I have seen in over forty years of house building and remodeling. They even found a problem with plumbing vent covered up by earlier contractor. In short, they are the best.

Burlingame Contracting
Burlingame Contracting
We are a new local business with 30 years of experience in the industry. We can act as General contractors on a large project or take on smaller sub-contracts. Depending on the job we bill for time and materials, or a lump sum total with 40%-50% due at signing of the contract
"Paul Burlingame (and team) constructed a basement garage and attached ADU on the side of our 100 year old house - no small feat at all. Initially we were a little guarded because of all the horror stories you hear about shiesty contractors, but our experience with Paul has been nothing but positive throughout the entire build. He has a keen attention to detail and values good quality work. For example, there were a couple crucial details that were not described by our engineer, and Paul worked hard to determine the right course of action. In the end, what he came up with was better than we could have imagined. Not only is he personable and a knowledgeable contractor, he has an eye for aesthetic which was a delight as we discussed design options, from trim details to pergola hardware. In the end, Paul and his team built us a stunning 800 sf 2 story ADU and 400 sf basement garage, that feels spacious and contemporary while beautifully tying together with the exterior of our existing 1920s Tudor Revival home. I can not recommend Burlingame Contracting enough! Thank you Paul!!"

"James and his crew at Cox Custom Remodeling did a great job with our bathroom remodel. Our house was built in 1900 and the nonstandard framing made things more complicated. His lead, Dan was particularly great, taking the extra time to understand components we picked that were new to him. James always had a positive attitude, showed up when he indicated and got things done. Low dust, protection for floors and respect for the rest of the house while the construction was going on. James also provided the best tile guy, Eugene, that did a fantastic job with natural stone and the complicated very fragile mosaic. We would definitely use Cox Custom Remodeling again. Great job guys!"

FAQs for treehouse building projects in Mount Vernon, WA
The average cost to hire a handyman ranges from about $40 to $140 per hour. Average project cost ranges between $180 and $700, but the cost per hour and per project depends heavily on the type, size, and complexity of the project. The pro’s experience level and your location also factor into how much a handyman charges per hour or per project. You can also expect to pay higher rates or additional fees for emergency services, or around periods of high customer demand, like holidays.
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
The cost to build a detached garage for two cars costs about $26,400 on average. Prices range from $19,200 to $33,600, depending on your location, the garage size, height, materials, and site prep required. Additional cost factors include any plumbing, electrical wiring, and insulation. If you need to build a concrete foundation for a new detached garage, you can expect to pay $1,000 to $8,600 for this essential addition.
