Hiring us for general contracting means you get more than just someone to manage your project—you get a partner who cares about the details as much as you do.

We take on only a handful of projects each year so we can give yours the attention it deserves. Our cost-plus billing model ensures full transparency, so you’ll always know where your money is going. And because we’re selective about who we work with, you can trust that we’ll be fully invested in delivering craftsmanship, clear communication, and a seamless building process from start to finish.

We offer consulting services for homeowners who want expert guidance without committing to full construction. This can include project planning, material recommendations, budgeting and estimate creation, mapping out timelines, or simply having a professional in your corner to help you make informed decisions.

Consulting is a great option if you’re managing parts of the project yourself, working with other contractors, or just want a second opinion before moving forward (on a renovation or even purchasing/selling a home). Our goal is to save you time, money, and stress by giving you clarity and confidence in your project.

Yes. Our estimate fee varies based on project scope and complexity, and we discuss the specifics directly with each client. We charge for estimates because of the detailed planning, research, and accuracy involved in preparing them. We don’t just throw together random numbers…we spend the time to get accurate pricing for your specific project and choices.

Should you choose to proceed with us, the estimate fee is applied toward your overall project cost.

Although New Hampshire does not have a state-level license for general contractors, we make sure to stay up to date on building practices, building code regulations, and other necessary aspects of the general contracting field. We are also fully insured, and go above and beyond to make sure that your project is code compliant. We also pull all necessary permits, if applicable to your project.

At Mattson's Carpentry LLC, we take pride in being a TrexPro certified contractor. In order to earn the TrexPro title, contractors must undergo rigorous training and adhere to strict installation requirements and program guidelines. In other words…our decks had to be inspected and meet high quality standards.

While we don’t offer a formal warranty on our services, we’re committed to your satisfaction and stand behind our craftsmanship.

If you encounter issues with your renovation beyond normal wear and tear—provided it’s not due to negligence—please don’t hesitate to reach out. We’re more than happy to make a site visit and discuss potential solutions or any necessary repairs.

For Trex decking and railings, we do take extra steps to ensure your peace of mind. We register your TrexPRO warranty (this includes a labor warranty) with for all Trex products used in your project, so you benefit from their support with your product as well.

We take on only 4–8 projects per year, allowing us to focus on delivering exceptional quality and detail.

Because we’re selective about the clients we partner with, we cannot promise an immediate start date. However, if we determine we’re a good fit, we’ll add your project to our schedule and communicate clear next steps.

Sure do! All of our customers have the option to finance projects through Acorn Finance!

All of our quotes and invoices include a link to financing options through Acorn. Acorn connects you with multiple lenders, allowing you to compare loan offers with competitive rates and flexible terms. Checking your options won’t impact your credit score, and you can get approved for up to $100,000 with fast funding to keep your project on track.

We operate on a cost-plus billing model. This means you pay the actual costs for labor, materials, and subcontractors, along with our agreed-upon fee. We believe this approach is the most transparent and fair way to run a project for both parties—it eliminates inflated fixed bids contractors often use to “cover their butts”, while giving you a clear breakdown of exactly where your money is going.

It also allows us to easily adapt as your project evolves or if you change your mind, ensuring accuracy, flexibility, and accountability from start to finish. Please feel free to reach out if you have questions about this.
