Customization options are based on your preferences, needs, and budget. Some common customization options are size and layout, materials, doors, windows and skylights, electrical wirining and lighting, insulation and climate control, security features, custom features, and exterior design elements. 

What size of garage am I allowed to build?

The allowable size of a garage that you can build on your property in Montgomery County, Texas, can vary depending on several factors, including local zoning regulations, building codes, and specific requirements for your property.

“This is the second time we used this contractor. This time it was a total full bath remodel and a poured patio. The quality was good, they are easy to work with and the project came in on time and under budget. We highly recommend Sullivan Construction Company. Because of a positive first experience we did not hesitate to call for the bathroom. They seem to be able to accommodate any request. They are as stress free as remodeling can be.”

“The Mikes (as they came to be known in our home) were great. Their crew was professional and very efficient. In addition the roofing, we had our siding replaced and painted. We also had our back patio rebuilt. The project was completed to our total satisfaction and slightly ahead of schedule. For any future projects, Sullivan Construction will be one of the first we request a quote from, and given our very good experience will be the company to beat. I have recommended Sullivan Construction to 2 friends already and have done so with no reservations.”

“I had an apartment added to my home for my mother. Not only did Sullivan Construction have the most economical price, but the quality of the work was excellent. Both Mike Sullivan and Mike Huetter were extremely responsive during the construction, following up quickly with any questions and issues I contacted them with. Of particular note is the quality of the custom cabinets that were required due to space constraints. I would strongly recommend that Sullivan Construction be considered for building projects.”
