Stonework & Windowcill Repair

Stonework and Stone windowcills can withstand all the stresses and strains a home inflicts upon it. They provide impressive protection for a structure as well as keeping the shape of the window from warping. Having stone windowsills means that your home has classic, elegant furnishings and is protected from all the elements; that being said if your stone windowsills and doors are damaged there are aesthetic and structural problems occurring.

If the cracked surfaces are neglected and water can leak through the crack (you may not see the water leaking, it may be minimal), and cause the crack over time, to expand, this means additional repairs in terms of replacing the stonework, plasterboard damage, timbers rotting, and even electrical problems. Instead of a small cost, all of a sudden your costs could go through the roof by having to hire a few different companies. Long-term water damage results in harmful effects such as large scale damp problems like mold and mildew. Not only will water damage affect the structure of your house, but it will also affect your health! It doesn’t have to be this way if you take the time to handle the problems as they arise.


Furthermore, damaged stone windowsills impact the aesthetics of a home, and depending on the nature of the damage it could irreparably harm the resale or assessed value of a home. That’s why it’s important to take care of cracks when observed. These small repairs could save you replacing entire area the stone windowsill covers.
