"Hired G&R to fix up my deck, stain it, and paint a shed. The work involved replacing all of the horizontal hand rails, and tightening the floor boards. G&R stained the entire deck by hand (including the lattice work). Gave me a good price and stayed with that price. The deck was 35 years old, but you couldn't tell by looking at it now. My neighbor hired them to do some landscaping work after seeing them work on my property. Willie was easy to work with. Would definitely hired them again."

Basement Waterproofing questions, answered by experts

Other types of home improvement grants available are for those with very low-income housing, elderly people needing assistance, older adults, and veterans. These grants can range from helping with accessible modifications to improving critical issues that may affect the resident’s health or safety.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

Yes, you can over dehumidify your house. While you may prefer a dryer climate inside, the elimination of too much moisture in the air can lead to an extremely dry environment that can affect those with respiratory and skin issues. Strike a balance between eliminating excess moisture without making your home feel like a desert. Most modern thermostats show the humidity levels for guidance.
