"We hired this company. I don't mind paying but when they missed so many areas. It's very frustrating and I have to finish the job myself. Anthony promised a great job and so didn't Nicole. I sure didn't even get a good job. The hand railings are super rough, and where the pressure washer chewed up the wood it was never fixed. It was definitely a hack job. I was promised over the phone a walk through at the end. It never happened. Couldn't communicate with the workers. I couldn't understand them. Definitely the pictures that they posted on other jobs don't match what I paid for. A very disappointing experience with this company. I would shop around.. plus I included Anthony in the last few emails and he couldn't even respond back. Awful !!! The handrails was addressed in after the power washing. The owner needs to go back and see the truth. I have the email saved!!!! Give me your email and I would be gladly to send it you!! You shouldn't be sparky when your team hacked my deck. I will be re-doing myself. Such a joke of a company."

"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

"These guys did a great job. Our deck has a lot of railings and posts, and it is a bit of a pain to power wash; but they cleaned it down to the last rail. They even did the grill cover and mat. They also got rid of all the tree sap and drippings on the fencing. They were a couple of minutes late because they got caught up in rush hour traffic, but they made up for it by power washing some things that were not included in the original estimate at no additional charge. Their pricing was competitive with all the other estimates I got. Definitely recommend."

"Do NOT use this company if you want a quality paint job. Certapro breached the contract and did not provide services specified in the contract. We printed the contract to show the painter before he started but he still failed to comply with the contract. Painter came with wrong paint, failed to do a coat of primer as specified, was unaware he was to paint the wood trim around 2 ceiling windows (also specified), paint coverage was very uneven & left large areas appearing as gray shadows next to areas that were painted more heavily, did not cut edges of room evenly, etc. Additionally Certapro painter damaged a section of dry wall on his last day. Photo shows the way he left it. We reached out to Certapro owner Scott, the office manager, and our salesman Matt with a detailed email and photos. Waited over a week but had no response from any one. Called our salesman - waited over a week again. Very poor customer service. Very poor quality of work. Spent a week repairing the substandard work ourselves. Absolutely do NOT recommend this company."

"Very pleased with the work done by Jonathan Fiske. Jonathan delivered the door which we painted ourselves. When it was ready, Jonathan came out within a few days and installed the frame, door and moldings in one day. He also replaced the alarm sensor, made sure proper flashing was installed and took the old door away. He answered all questions that we had. It was a pleasure working with him and would recommend him to others."

FAQs for deck, fence, patio or porch clean and seal projects in Laconia, NH

You should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.
