Masonry Maintenance (Holly's House)

Masonry Maintenance

Normal masonry maintenance consists of cleaning, re-pointing, and sealing. In the case of Holly’s House the masonry has weathered for over eighty years and will need to be thoroughly cleaned and dried before the mortar can be matched for re-pointing. I have found that if you re-point (replace missing mortar) before the masonry is cleaned, you run the risk of a bad mortar color match. With masonry of this age the mortar was mixed with sand from a near by riverbank. The river sand contained a lot of small shell and gravel pieces giving the mortar a rough texture. To keep our re-pointing from looking like a “patch job” the color and the texture need to match the old work as close as possible. Matching old mortar and the general restoration of old masonry is defiantly an art. We are very fortunate to have Norman (Chub) Garrett on our team. Chub has over fifty-six years in the masonry field and was one of only three Masons to receive the “Master Masonry Craftsmanship Award” in Virginia. Chub takes pride in being a living virtuoso of masonry history and restoration. Chub has restored or been the go-to-guy for many historic landmarks in Virginia.
We are going to start cleaning the masonry on the front porch area of the house. As you can see from the pictures below, the masonry has been weathered and stained by mold, car exhaust, and dirt. New masonry requires strong chemicals such as Muriatic Acid to clean mortar off of the masonry surfaces, but in our case there is no mortar on the masonry surface, only dirt, mold, and car exhaust. To remove this dirt, mold, and car exhaust we are going to use a biodegradable soap and a low P.S.I pressure washer.
This will get the job done and keep the plants and flowers safe.






























Let's start the cleaning!
See you tomorrow.
