Experienced professional - Over 35 years of professional contract work completed. I specialize in structural repairs including Field Stone Foundation - Sill Replacements, Lally Columns, Footings, Beam Replacements - Antiques Bought - that are being listed to be sold. I am fully licensed and insured. Services do not include crack or foundation repair.

"Rene is the best! We reached out to Rene about structural issues on our old home. He responded promptly and scheduled a visit within a few days. He knew just what to do to address some sagging floors and areas of the house that weren't correctly supported. He did all the work himself (he sometimes has his son work with him). I have no idea how he was able to complete all the work on his own, especially pouring new concrete footings in a very small crawl space! He is a machine!!! He is meticulous in his work and really goes above and beyond. He left our basement cleaner than when he started!!! He’s a super nice man and it was a pleasure having him work on our house."

Haydenville Woodworking and Design, Inc. is a well-established firm offering comprehensive construction services. The business was started over 30 years ago in a small out building turned into a shop behind the founder’s home. It quickly expanded from those meager beginnings to a construction company based in South Deerfield, MA. Two longstanding employees purchased HWD from the founder in April 2017.

We are a small owner operated company, I Keith Kapusta, am onsite everyday doing the work myself, which keeps the quality high and price low. I'm also one of only a handful of registered professionals with Trex Decking. This means if I build your deck Trex itself backs my work with a 25 year warranty. You can see more information about this at Trex.com. I'm also licensed in CT and MA. My business is proud to hold an unrestricted license in MA. It is the highest license one can earn in this trade. This license puts me ahead of most builders in CT. That is because in CT there is not a test or any requirements to get a contractors license. It is as simple as sending the state a fee of $220.00 and they send you a license, allowing just about anyone at all to be a contractor in CT. In MA they require at least 3 years of on the job experience and a 5 hour test. I'm also licensed and fully insured and refuse to every let a client of mine be anything other then 100 percent thrilled with the work. I love what I do and it shows in my work.

"Keith did a great job helping us obtain the building permit, explaining the decking options, and designing the deck. The deck completely covers old concrete steps and makes entrance into our home much easier. Keith used Trex material for the deck, which is maintenance free; he negotiated a good deal with the supplier for the color which closely matched our other deck. He suggested a local electrician for us to consult about lights along the stairs. Keith communicated with us in a timely basis and we always knew his schedule. We would not hesitate to hire Keith again for another project."

Custom Home Builders questions, answered by experts

Yes, a home builder should have a builder’s license and insurance. States have different requirements for builder’s licensing and certifications. Be sure to check our state licensing tool to review your local home builder licensing guidelines.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

Yes, you can finance new construction using a construction loan or a construction-to-permanent loan, or you can use a home equity line of credit or a cash-out refinance if you’re building a second home. Some mortgagors may have restrictions on DIY house builds, so be sure to check that you can get financing before starting your project.

The early stages of building a house are harder than the later stages; laying the foundation and framing the house are two of the most challenging steps. However, it varies for everyone. Some people have difficulty installing HVAC, plumbing, and electricity, while others find it harder to plan the house and secure the necessary permits. 

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits
