Not only do home additions add value, but more importantly they add comfort to your life. Whether you are looking to add a new spacious master bedroom, a luxurious living room, or an attached garage, Diamond Hill Builders has the experience and expertise to help you with your next home addition project.

If you are like most of our clients in New Hampshire, you have limited property, have very specific zoning laws to abide by and are excited to add that much needed space. You are probably a bit nervous too because building an addition is an investment and you want to make a good hiring choice.

We understand that choosing the right general contractor for your new room addition or home addition may be one of the top five decisions you will make in your life. Diamond Hill Builders has a rock solid reputation, we are engaged in our local communities and our start-to-finish process is proven to reduce costs and virtually eliminate costly project delays and unpleasant surprises that plague most projects.

How Do I Determine A Fair & Reasonably Priced Bid?

Price is certainly a factor you need to consider but if it is the primary factor and you feel pressured to hire based on a budget, you are likely to make a decision you will regret. In comparing proposals from your contractors the hardest thing to do is to make an apples-to-apples comparison. We encourage homeowners to be careful accepting a price that is 15% below the bids of other reputable builders because the bid will likely lack the same quality materials, installation methods or warranty. If you accept that bid, be prepared to also accept lower quality or an increase in price after the demolition is complete and there is little chance to fire the contractor, even if they demand more money.

As you explore our website you will most likely discover that there are many things to consider when choosing a contractor to complete your project.

The home construction industry in the New Hampshire seacoast area is very competitive and we thank you for the opportunity to earn your trust and your business. If you are ready to fulfill the vision of your dream home, please give Diamond Hill Builders the opportunity to add you to our growing list of delighted homeowners.
