"Adam is the kind of service technician you want in your house. I'm the kind of customer who wants to understand what's going on, why something broke, how I can prevent it, what are the alternatives, etc. He walked me through everything, explaining what he was doing as he was doing it, and stopping periodically to dive deeper into the details as I had questions. My AC needed a charge of coolant, but the air handler in the attic was also in a deteriorated state, with rust buildup and mold present. Adam showed me everything he was seeing and explained its significance. He also explained that our system is using a type of coolant (R-22) that is being phased out and that will become increasingly difficult to find. We got the AC working again for now, but it sounds like we need to replace our system. I will definitely be reaching out to Cotti-Johnson about that, and I hope the installers I get are as meticulous and knowledgeable as Adam!"

"I recommend this wonderful company without any hesitation. I first contacted Wood Trades LLC seeking a deck quote in September 2024, and John and Karin came out the very next day. From day one, John and Karin provided impeccable service. I cannot say enough wonderful things about their communication, transparency, honestly, and reliability. All current insurance/contractor licenses were provided up front, and any change in cost was documented through clear contracts. In addition, they patiently navigated me through a difficult permitting process from start to finish. Once the work was started, I had a gorgeous new deck in just over one week. I cannot thank this company enough for gaining, and more importantly, maintaining my trust through this project. I certainly look forward to working with Wood Trades again, and highly recommend their services to anyone seeking high quality results from a wonderful company. Exceeded expectations!"

"Amazing team and service! We had flooding in our basement and as you can imagine it was extremely stressful. Kyle and his team made sure we were comfortable every step of the way. We ended up having a late service, due to other clients they had that night. Preston showed up at 730pm with smile and determination to fix our issue. He was here until after midnight, trying everything he could. Unfortunately, we had to resort to calling the city for assistance at the sewer. They recommended a plumber and helped get though a major issue at our house. Thank you Zoom Drain."

Subcontractors questions, answered by experts
  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

Common pitfalls include underestimating the cost of site preparation, overlooking permit and utility fees, and not setting aside funds for unexpected changes. Change orders during construction can disrupt your budget. It’s best to plan a detailed budget, obtain multiple quotes, and include a 10% to 15% contingency fund for unexpected expenses.

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.
