"This is the 2nd time I've used Freeborne and I would definitely have them back again. They built a 12' X 16' enclosed room on a 2nd story deck and it came out great. Lenny, Scott and crew knew what we wanted and exceeded our expectations without over complicating the project. There were no budget surprises either. The amount we discussed at the beginning was what we were charged. If I could I would use them to do projects inside of the house!"

"Right from the outset, I found Bob very professional and accommodative to my request to keep the project within my budget. Importantly, they were punctual. I liked his approach to remain transparent about meeting expectations. There were a couple of spots where cleaning would not have given desired results. Setting up my expectations, a friendly approach and completing on time, using good chemical agents has left me satisfied."

Deck Cleaning questions, answered by experts

In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Pressure-treated lumber is one of the most affordable types of decking upfront. This material is widely available, so you can usually find pressure-treated lumber at almost any local home improvement store you visit. Keep in mind that wood requires a lot of upkeep with repainting and restaining, so any kind of wood may be more expensive in the long run than something like PVC decking.

For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.

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.
