"Excellent. We added a bathroom and a bedroom, took down paneling and completely redid the family room. These guys did all the electrical work, plumbing work, flooring, painting and everything else. Amazing communication, stayed on budget, worked very well with us and the work was done quickly and exactly as described. Any issues were immediately dealt with. Any questions were immediately answered. Would absolutely work with these guys again and would recommend them!"

"Timber and Megan are consummate professionals who are timely, hard working and detail oriented. I was very fortunate to have them realize a project that was centered around creating an in-law apartment in an existing space in my home for my father. They worked with me every step of the way which resulted in a collaborative design with a nautical theme. The end result is stunning and everyone who sees it wants to live in it! Thank you Timber and Megan for making my vision a reality."

"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."

"No 2-hr. presentation to sit through. No sales-speak. Just a small contracting company bent on doing quality work for an affordable price! Start your search by calling Karol Kurkowski of KBK Construction and save yourself a lot of time. 9 times out of 10, he'll answer the phone! Who does that these days? Karol and/or Zibi were on site every day usually starting at 8:30am. Being an old house, nothing was square. It was necessary to pour a self-leveling concrete floor, which took a few days to dry. Even so, they completed the whole job, surprises and all, in under 2 weeks. Many people like tile. I'm not one of them. I wanted a MAAX 80" acrylic tub wall kit, from tub to ceiling. Who knew that it would be so difficult to find a contractor to install it? I'm so grateful that Karol agreed to and did a fine job. Besides doing quality work for a reasonable price, they were a pleasure to work with - always polite and conscientious, and cleaning up at the end of each day."

"We had an old deck that needed to be replaced.  When the old deck came down we had to do some grading of the soil.  Jim worked with us to schedule himself and the tractor work to make this happen.  The new deck exceeds our expectations.  Jim has great attention to detail and made sure that every part of the deck looked correct and pleasing to the eye.  We added string lights and outdoor lights to the project and he was happy to add that as well.  It is very hard to find people who are excited about your project and take ownership of it.  We found that in Jim and his team!  We are SUPER happy and would reccommend Jim to anyone.

"Working with Wes and his wife Aimee was a pleasure from the very first minute. Both are very professional and courteous - so refreshing and different that it made an immediate impression. You can have complete confidence in Wes to get the job done - done well and done on time. Now that I have found A&W Carpentry there is no reason to look any further. The other reviewers were all right. You'll see!

FAQs for addition to existing structure building service projects in North-westchester, CT

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
