"Maria and her team were very professional and courteous. They worked well together and hardly ever took breaks. This team hand brushed the entire house and it looks great. Clean-up was well done too. Maria was one of the only painters in the area that was willing to work us into her very busy schedule. She knew we had a very strict timeline and the job had to be finished quickly (we had renters arriving). Despite all the rain we had last week and an unfortunate personal issue, they got the job done just in time. I'm grateful for Maria and her team and their diligence. We would recommend this team and would definitely hire them again. Thanks Maria!

"I used Dean for two jobs and was impressed with how polite and knowledgeable he was. If he was not able to arrive at the specified time he informed me. The first job was a reshingle job for my daughter which was completed in a timely fashion without a hitch. The second job was a teardown and shingle for my home. There were a couple of glitches due to incompetence on the part of a worker who is no longer with him. Dean immediately went above and beyond what was necessary to correct these errors and I am confident that should any other problems arise he will take care of them. I will certainly contact him if I have any further work to be done"

Deck Cleaning FAQs, answered by experts

The problems with composite decking include a high rate of expansion and contraction from temperature swings. This characteristic can cause boards to split, delaminate, or peel. In addition, significant movement can cause shrinking, warping, twisting, and bending. For this reason, you should minimize moisture and ensure proper airflow below your deck.

There are several methods for attaching stair stringers to a deck. The best way is to bolt the stringers to the deck joists using three carriage bolts in a triangular pattern. This method offers the sturdiest fit for stairs that won’t budge. Alternatively, attach the stringers to the deck rims using lag bolts or to the posts using adjustable slope hangers.

Footings for ground-level decks need to be at least 12 inches deep, and some areas require them to be even deeper. A standard range for deck footings is anywhere from 12 to 48 inches. The minimum footing depth is determined by an area’s frost line and soil conditions. If you’re unsure how deep to install deck footings, check local building codes to find the minimum footing depth in your area. 

Many people say the best composite decking is Trex, TimberTech, or Fiberon. These brands have formulated composite deck boards to withstand the elements and hold up over time. Each offers a range of product lines varying in durability, price, and appearance. Compare their different composite decking offers for cost, looks, and features before deciding on a product.

It’s best to use two screws to secure deck boards into every joist. Securing the boards to every joist makes the deck more structurally sound, while using two screws on the outer sides of the boards can help prevent warping and cupping.
