"We worked with Prudential at the beginning of the year and they did such a great job that we decided to work with them again and boy did we go all out. We took the leap, got a home equity loan and did everything we wanted to do from siding to decking to even closet work. We could not be more pleased if we tried. I did get other quotes in the beginning, but you would not believe the number of contractors that do not respond to calls or emails. I had two contractors that came out and never even sent me over a quote. Thank you Shannon for always keeping us in the loop. I would give you all a higher grade if there was one."

"Working with Pro Warrior Construction on our enclosed porch was a fantastic experience. Yann, the owner, was hands-on, professional, and made the entire process smooth from day one. He kept us informed, stayed on schedule, and made sure every detail was handled properly. The craftsmanship and overall quality of the build really impressed us. The enclosed porch turned out beautiful and has become one of our favorite spaces in the house. It’s clear that Yann and his team take pride in their work and genuinely care about delivering great results. We’re extremely happy with the outcome and would confidently recommend Pro Warrior Construction to anyone looking for dependable, high-quality construction services."

"True north has done many projects for us and recently did our back deck which ended up changing into a screened in porch. They are always on time, professional, friendly and have worked with us making adjustments and changes. The workmanship is very good! I d hire them back for any future projects."

"TJ responded to my request within the hour. He came out the same day, and gave me a quote and timeframe. TJ is friendly and professional. He updated me when the materials were ordered and when they would arrive. He was onsite the same morning and did a fantastic job. I highly recommend TJ. Our front porch looks fantastic"

"Im am very happy I found this company! Thanks Nick and Marshal for the outstanding work. Their quality/detail is unbeatable! They went above and beyond to meet my expectations. They had a tough job to fix a deck that someone else built so poorly. They explained what could be done, what could improve but also what couldnâ t be fixed entirely. The only thing was that my budged was tight, but I also requested other things outside the quote he gave me. The only thing I would do different next time was to purchase all the items in advance and ask them to install. That would create less trips for them to the store prior to initiate the service/project. Thanks Nick and Marshal with everything. I hope to hire you next time."

FAQs for deck or porch projects in Portsmouth, NH

Northern white cedar is the most affordable cedar decking type and delivers exceptional value with low material expenditures. This option provides proven cost efficiency, meets essential durability standards, and is easy to paint or stain to meet your aesthetic preferences. By comparison, eastern red and western red cedar supply extra longevity and richer texture for a modest increase in investment.

Yes, cedar is a great choice for decking material. It offers a timeless look and natural resistance to decay and insect damage. Keep in mind that cedar requires regular maintenance, like resealing and cleaning, to keep it in top shape. With proper care, a cedar deck can enhance the appeal and value of your outdoor space for years to come.

No, cedar is not pressure-treated because it contains oils and tannins that naturally resist insect damage, rot, and decay. With regular maintenance, including annual cleaning and resealing every two to three years, cedar maintains its structural integrity and pleasing appearance for 10 to 15 years or more. Cedar’s natural durability, without need for chemical treatments, makes it an environmentally friendly option for outdoor structures like decks.

You should stain or seal your cedar deck every two to three years to maintain its appearance and longevity. This helps protect the wood from moisture, mold, and environmental damage, preserving its natural color and extending its lifespan. Regular maintenance keeps your outdoor space both attractive and durable season after season.
