Chimney Cap (Question)

Hey Al,

We recently purchased a thirty-year-old house that has been completely updated.

Our home inspector said that the chimney does not have a cap. He also said that the chimney was used for the old furnace and the old water heater. Both have been removed and replaced with new units that have their own venting system.

Since the chimney is no longer being used for anything, should I still put a cap on it?

Can you help me understand?

Deck Staining (Answer)

Hey Mark,

It is difficult to put a time factor on when it is safe to seal, paint or stain newly constructed porches or decks. What really matters is the moisture content of the material. The moisture content for paint, sealer, and stain applications should not exceed 14 percent. To determine the moisture content, you will need to rent a moisture meter. Some of these meters have probes that look like pins; they are only intended to touch on the surface for the moisture reading, not actually inserted into the material.

For older decks, it’s a bit easier to determine when to stain or reseal. A simple test would be to check the deck after a short or moderate rainfall – or pour a half-cup of water on slowly. If water is beading on the surface, the deck is sealed and protected. If the water is absorbed quickly, it’s time to reseal.

There are many brands and types of deck finish; none is perfect for all situations. Their success lies not in the type of ingredients – or the price – but in how well they penetrate the wood. The more they soak into the wood, the longer the finish will last. Be sure, however, to get a sealer with ultraviolet protection, since sun can be your deck’s worst enemy.

Deck Staining (Question)

Hey Al,

I built a new house with a deck in May 2003. I have heard that you shouldn’t stain your deck or porch for a year, but I would like to do so before winter even though the wood is pressure-treated (the new kind).

Which is correct?

Not Enough Circuits (Answer)

Hey Mattela,
I recommend that you consult the electrician doing your work. Or, if you are knowledgeable on wiring and the safety precautions of doing the work, you can do the work yourself.

My recommendation is to run two twenty-amp circuits. Put half of your outlets on one and the other half on the other. If you are doing this yourself, don’t forget to use 12/2 wires. For safety, never attempt a do-it-your-self electrical job without the proper knowledge of wiring methods and safety precautions.

Not Enough Circuits (Question)

Hey Al,

We just moved into a larger house with a workshop area. It is large enough for my tools, but it only has a 15-amp lighting circuit and no outlets. I am upgrading the electrical service to run my power tools.

I have a table saw, a bench grinder, a vacuum cleaner, a table sander, and a drill press. Between my son and me, we may run two of these tools at a time and I want the circuits to be adequate for this, without tripping breakers. I need to install six receptacles, but I need to know how many circuits to put them on and what amp breakers to use?

Can you help me?

Black Staining on the Roof (Answer)

Hey Tony,

The black staining is caused by the growth of algae and fungus spores that land on your roof. Trees do not have to be nearby for these air-born menaces to set up camp on your roof. All they need to grow is the nutrients from both the dirt on your roof and the limestone granules on the shingles. Heat and moisture on your roof will help them turn your whole roof black.

Roof shingles come in a wide variety of quality as indicated by the prices. The higher quality shingles have treatment to prevent algae and fungus growth. This treatment involves adding varying amounts of copper and zinc granules, and petroleum distillates on the shingles. Cleaning and controlling algae and fungus growth can add to the life of your roof.

If you choose to clean the roof yourself, be careful of products that are just bleach or chlorine. This type of product can leave your roof streaked and can also dry out the singles and cause premature cracking and a shorter shingle life. Some of these products also will kill grass and shrubbery. Read product labels carefully and follow the application directions. Most of all, be careful working on the roof, because you can cause damage to yourself and the roof.

Another alternative is to call a qualified roof cleaning company. You still need to ask if the products they use will cause streaking or grass and shrub damage. Roof cleaning companies can also provide preventative maintenance services that can prevent future algae and fungus growth.

Black Staining on the Roof (Question)

Hey Al,

We live in a twenty-year-old ranch, with a two-year-old roof. We had the new roof done in a light colored shingle.

Now we have noticed black staining starting near the peak and running towards the edge. Our house faces south, but the stains are on both sides of the roof. We are not close to trees, so we cannot figure out what is causing these stains.

Can you tell us what these stains are and how to get rid of them?

Tony
