Customers say: Super punctual

"I can't speak highly enough regarding Jeff Lemires's work. I've worked with various contractors throughout my career and have never come across one who is not only thoroughly trained and talented in the trade but who is also scrupulously honest and trust worthy. I have reviewed a number of individuals with whom I've conducted business in the upper valley but never anyone who so richly deserves a perfect score.. This gentleman deserves only those clients who understand and appreciate quality at its best at a fair and reasonable price.

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"Oliver was very polite, courteous and flexible to help me keep the project on track. Other contractors caused him to change his schedule with me twice and in the end he came up on a Saturday to finish the job. His prices were fair, his craftmenship was excellent, and his knowledge of more than tile install was invaluable on this job. He was also quite helpful giving me suggestions when I asked for them. I will definately go to him first on my future project needs."

Unfinished Carpentry FAQs, answered by experts

You can choose 5/8-inch plywood or 3/4-inch plywood—anything thinner than these sizes may not withstand the impact of debris propelled by strong winds or can be easily torn off by intruders. Remember that the durability of the wood board is crucial, particularly for safeguarding your windows during severe storms. The effectiveness of using wood boards for protecting the investment you made in your home relies on using the appropriate material and ensuring proper installation.

Yes, ceiling joists are typically load-bearing. However, their primary function is to support the weight of the ceiling and loads applied to it, like lighting fixtures and ceiling fans. They can also help support the roof, especially if they’re part of truss systems. Remember, the load-bearing capacity of ceiling joists depends on the material, size, and space between them. 

The cost to convert a carport into a garage averages about $22,000, ranging from about $15,000 and $55,000. Additional cost factors to consider include size, time of year, and how much of the carport you can reuse. Other cost factors include the kinds and amounts of materials used, such as:

  • Add insulation: $1 per square foot

  • Add drywall: $1–$3 per square foot

  • Add window: $450–$2,000 per window

  • Add outlets: $75–$500

  • Add garage door: $250–$11,200

  • Enclose framing: $5–$13 per square foot

  • Replace roofing: $1,000–$2,000

A-frame homes are on the smaller side. While there’s no set square footage amount it has to be, it will usually come in around 1,000 square feet or smaller.

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.
