There is almost no difference between cleaning a stained deck and an unprotected one. This is primarily because the wood stain placed on wooden deck planks are considered permanent, which means there are essentially few commercial cleaning solutions that can remove the stain on the wood. Therefore, when you think about cleaning stained decks, you should focus more on retouching or protecting it again. The most basic concern therefore in learning how to clean a stained deck would be its protection and the cost it takes. Here are some important things you must consider when cleaning.
1. DIY or Professional Cleaning
Protection from stain, ultraviolet rays, and mildew can be considered as some of the most vital benefits of stained decks. There are many sealer products in the market that can deliver all of these through tinting, coloring, and UV protection.
If you consider cleaning the deck yourself, supplies can run from $20 up to $250 based on the brand, quality of the stain, and of course the size of the deck to be treated. Pressure washers can either be bought or rented, and will set you back another $40 to $200. Be aware though that some professionals believe that high-pressure washers can actually damage your deck. You also need to dedicate some time and much patience to complete the cleaning process.
The cost of hiring professionals to do the cleaning would depend mostly on the size of the deck. Some professional fees start for as low as $0.50 a square foot and can go to as high as $2.50. The condition of the deck will also come into play because of the amount of preparation work that has to be done. Staining cost can run from $2.50 up to $7 per square foot or sometimes even more depending on the complexity of the work and other features to stain.
These figures of course do not include any repair work that must be done or if any additional handwork should be included in the project. Sometimes the costing of professionals can vary depending on your actual location. These amounts can give you a fairly good baseline of just how much it will cost to clean your stained deck.
2. Scope of Work
When cleaning a stained deck, you will need to remove all furnishing that are on the deck. This is of course to allow for proper preparation of the deck and to do any repairs or sanding if necessary. The stained deck must be cleaned with water and allowed to completely dry for about 48 hours before a fresh coat of stain is applied.
Unless you are fairly skilled at handling a power washer, it is highly recommended that you wash by hand or hire experts to do the power washing. This is to make sure that you do not accidentally damage the stained deck and cause additional expense. If you have plant decorations that cannot be removed, make sure that plastic sheeting is used to cover them before applying stain.
Direct sunlight can help to shorten the drying time, but it is not always the best for your stained deck. Normally, temperatures not more than 80 degrees would be the most ideal. This means that you should schedule this type of work either in the fall or during springtime. Make sure that the stained deck is completely dry before using it again.
3. Cost of Washing
On the average, having a 100 square foot deck pressure washed would cost about $325 up to $400. This would normally include washing the partition, if any. Re-staining the deck will take much time because of the preparation process involved. Any rotted or broken boards must also be replaced. All of these would add to the timeframe including the drying time after power washing.
If you hire a professional to do the power washing, deck staining, and repairs if any, plus labor and materials, you are looking at a cost of around $325 to $500 on the average. The work can last anywhere from 3 to 6 hours. This price can vary depending on the area you are in.
All of these should be carefully considered on how to clean a stained deck.
