Of course you do, this is Houston. The ground and climate mixes in such a way here, that it causes your home to move and shift. We can repair these unsightly cracks in such a way that the drywall would be more likely to crack next to the repair, than to crack the repair itself.
One thing to consider, is having your foundation looked at by a foundation repair company to make sure it is in good order. One company we would recommend is Olshan Foundation. We have worked with them in the past. They are a good company. www.olshanfoundation.com
