"My wife and I were very pleased by the plaster work that was performed in our home by Robert Dell'aquilla Plastering. The owner and his workers did great work on about 5 different areas of our house, ranging from holes that had been punched into walls from previous electrical work, damage that had been done during storms and leaking gutters, and cracks in some rooms due to subsidence. In each case, the work was done professionally and completely, addressing the issues and leaving each area looking like new. The employees were very experienced and skilled, making some difficult repair situations look amazing. They treated our home like their own, even repairing some minor issues they spotted that were not initially requested. All of the crew were diligent in cleaning the rooms and closet areas that had been worked on. We found Robert Dell'aquilla Plastering by searching and researching previous reviews. We were very pleased with the work that they performed in our home."

"These guys are not only pros—they are true gutter artisans. After a decidedly frustrating experience with previous roofers, who were at best sloppy but in any case showed no pride in work, working with Ryan Hankey and Always Perfect Contracting has been a breath of fresh air. The work was a challenging replacement of a decayed and rotting box gutter on a circa 1850s historic home on a steep hillside with 36 stairs. There was no way to save the box gutter. Ryan and his team of Jeff and Dino worked long days in high heat and humidity to get the job done in two days. Not only did they replace the gutter, they remediated some of the sloppiness perpetrated by previous roofers at no extra cost. I got three bids on this project, and although Always Perfect Contracting was not the cheapest, the level of craftsmanship more than warranted the price differential. I cannot recommend these guys highly enough—7 stars (out of 5)."

"Sean and Dave are true craftsmen they are polite, honest, and pay close attention to detail. I was referred to him from my mother-in-law who he built a beautiful set of multi tier stairs for. Sean went over every step of the build asked for my input, listened to my opinions, helped me envision the project, accommodated a few of my needs and finished the job thoroughly before the quoted deadline. Me and my wife are so happy! Robertson Home Renovations went well beyond our expectations. It is a surreal feeling to have our dream deck completed in a weekend and at a reasonable price. I look forward to future projects with Sean and I will definitely refer him to anyone that is looking for a honest contractor that takes pride in their work! Thank you"

"Price and Vaughn agreed to pick up an exterior painting and carpentry job that had already been contracted to someone who failed to perform at the high level of quality that had been promised. We were impressed with their eye for detail, the professional business manner, their treatment of their employees, and the overall outstanding end product. We called them back for 2 other jobs, and will call them again without question."

FAQs for deck, fence, patio or porch clean and seal projects in Sewickley, PA

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.
