d. a. kinsella company was created to make great design accessible to everyone. Our philosophy has always been that strong communication and attention to budget allow us to achieve unique design and planning solutions for every project. DBA- d. a. kinsella company

"Great, Dave stayed within our budget and our addition looks like it was part of a whole new home construction. We were really impressed with Dave Kinsella's design concepts and the workmanship was high quality even though we were on a tight budget. Dave comes from a big family so he understands money and time constraints plus he wants his projects to look as aesthetically pleasing to his clients as possible. We would definitely hire Dave again."

James Finn, at Finn Builders, specializes in remodeling and home renovations. I run a company that allows you to impress your guests and enjoy the new style of a custom kitchen or bathroom. You will boast about your new space, even before we get finished. For over 25 years, Finn Builders has been the solution for many families upgrading their space into something spectacular and brand new.

"I have an extensive experience with Finn's builders (Chris, James, and Kenny) Over the last 3 years they have revamped my ranch style house with innovative ideas, and expert solutions: rebuilding walls and floors of a veranda, redesigning the interior stairs to the basement. They painted and re-organized the garage. They installed Anderson windows in 2 bedrooms and 2 bathrooms They repaired a walking shower, came up with a clever solution for an uncomfortable shower system. Likewise, they installed electrical outlets and lighting in the living rooms and painted 3 rooms with maximum efficiency and minimum fuss. I like their working style and their ingenuity. I rely on their team for keeping my house in shape and my mind at peace. I recommend them without reservation."

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.

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

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Craftsman-style homes are predominantly found in the Western United States, specifically in Southern California, where the style originated. Since the climate was mild and there was access to plenty of natural resources, Southern California became a hub for this style at its inception. That being said, if you consult with an architect near you, you can have a Craftsman-style home anywhere.

A construction-to-permanent loan is the most common type of mortgage used to finance a house teardown and rebuild. These loans include financing for construction costs and convert to a long-term mortgage once construction is complete. Check the terms of the loan closely before beginning work—there are often restrictions requiring you to use licensed contractors for all work.

Modular homes can go up or down in value depending on a few factors. In areas where real estate is appreciating, the value of modular homes is likely to increase, and vice versa. Additionally, the value of modular homes depends partially on the area. In cities where every other home is stick-built, modular homes might be considered a functional obsolescence, in which case they could be less desirable and go down in value. In either case, though, modular homes can still be a good investment, especially since they provide housing at a lower upfront cost.
