F. A. Q.
How hard is it to install?
Pretty simple! Our crawlspace doors are designed for both contractors and DIYers.
If you’ve handled home projects with tools before, we’ll guide you through every step.
Experienced tradesmen can expect to install our doors in under 30 minutes – quick, easy, and built to last.
What colors are available?
All of our doors ship as standard white. They are paintable using any PVC specialty paint.
Non-PVC dark paint can possibly warp large panels in direct sunlight, so use the good stuff!
Can you add foam board insulation?
Sure! Adding 2" foam board insulation is an upgrade available for any custom door for $25. Include the request in the notes box of your order, and we'll get it added.
Do I need to seal or caulk the door?
Don’t skip the silicone sealant! Sealing around your door keeps out drafts, moisture, and pests, protects the frame, and gives your installation a clean, professional look. Quick to apply and worth every second.

Customer Review
We installed our under-the-house access door today. We could not be more pleased! It fits perfectly and looks so much better than anything else we have tried. We also appreciate your prompt responses to our questions. We highly recommend this company and its products. - Gary A.
