Post Designers and Builders Does It All


Located in Manassas VA and serving Prince William County, Fairfax County and surrounding areas. Post is ready to help with you with a dream sunroom or screen porch. A sunroom adds beauty and value to any home. Screen porches add living space for three seasons and more. As with any renovation, room remodeling and building can also entail work that goes beyond designing the actual space itself.

Because Post Designers & Builders are general contractors who specialize in both a remodeling and contracting, we are able to undertake projects addressing specialty needs. Our simplified and streamlined design and building process enables us to complete jobs as timely and efficiently as possible.


Our Sunrooms Are Custom-designed and Built for Your Home


We are more than a sunroom or patio enclosure builder. We are a general contractor who will design and integrate your new sunroom perfectly into your home to maximize light and visual effects. Your sunroom becomes a beautiful and seamless part of your home, not just an attachment.

We also handle all the electrical, heating and ventilation, and structural modifications that other construction companies can't or won't do.
