Delaware siding maintenance

If you installed new vinyl siding on your home a few years ago and have noticed that it’s looking a little worn lately, you may be wondering how to go about maintenancing it. Well, don’t worry – our Delaware siding experts are here to help.


Generally, vinyl siding is designed to be low-maintenance and shouldn’t require much attention, but if you want to freshen up its look, we recommend giving it a good cleaning. Mix an ordinary gentle soap with warm water, then clean your siding with a soft cloth or long-handled soft bristle brush. Start from the bottom and work your way up, making sure to wash off all of the soap before it has a chance to dry.

If you want to pressure wash your siding, check with the siding manufacturer first; some manufacturers believe pressure washing is too aggressive for their siding. If you’re able to use a pressure washer, be sure to keep it straight so that you don’t spray water up underneath your siding.

Mold/Mildew Removal

Have you spotted some mold or mildew on your Delaware siding? Don’t worry – it’s easy to clean off. We recommend using a household cleaner like Windex or Clorox to gently remove the mold or mildew. You can also use a solution of white vinegar and water (30% vinegar, 70% water). For an even more powerful homemade solution, mix 1/3 cup laundry detergent with 2/3 cup trisodium phosphate and 1 gallon of water.


In order to protect your vinyl siding from stains and discoloration, make sure you keep your distance when spraying pesticides, cooking on the grill, spray painting, staining, or doing anything else that produces an airborne effect. Also, be aware that vinyl siding can be damaged by heat, which is another reason you should use your grill at a distance.

Siding Replacement

If a piece of your siding is damaged or has broken off, you’ll probably need a small siding replacement. Give us a call and we’ll come assess the situation. After we decide what’s best for your home’s exterior, we’ll work quickly to restore it back to its original state.


Vinyl siding that’s over 15 years old may have some noticeable fading after so many years. While you can’t do much to bring the color back, you could consider painting over it. Before you do, however, check with the siding manufacturer; some void their warranties if their siding is painted. If you get the “ok,” choose a latex paint so that the paint can flex with the vinyl’s movement. You’ll want to choose a light color for your paint – a color too dark can absorb heat and cause the siding to buckle.

Before you paint, clean your vinyl thoroughly (see above) and let it dry. Then, choose a time when the weather will be nice for a few days (you don’t want rain ruining your hard work) and paint each piece with a smooth, even coating of paint.
