you have questions

You might be wondering, "What are we up against? Why is my house, deck or fence looking so bad?" or "What is causing it to crack, warp, or even fall apart?".

The answer is relatively simple. No matter where we live or what we do to avoid it, virtually all exterior surfaces will succumb to the unsightly and degenerative affects of algae and mildew growth. There are many stages of algae and mildew. In its simplest form you will see basic black spores growing on the substrate (surface), and at its worst you will see it heavy enough that it can soften the surface beyond repair.  Moisture feeds the growth of algae and mildew, so the wetter the surface the faster the growth. Sun, rain, snow, and even shade are factors that contribute to the problem.

Is there any hope? Absolutely, and by taking a few simple steps you can not only reduce the growth of algae and mildew, but you can considerably extend the life of the surface! By cleaning it free of algae and mildew, followed by an application of the right coating, you will have it looking great and can rest assured that your efforts will go a long way in preserving the integrity of the wood for many years.

All types of wood such as cedar, pine, fir, redwood, pressure treated lumber, and even hardwoods need protection. As you can imagine, it is much less expensive to maintain it than it is to replace it.
