How can I get pricing on a door?
You can contact your local Therma-Tru dealer to request a quote.
What are the advantages of fiberglass over wood and steel?
A Therma-Tru fiberglass door looks like wood. But it won’t warp or rot like wood, or dent or rust like steel. And the inside is filled with an exceptional heat- and cold-resistant material that helps keep your home warm in winter and cool in summer.
Do you offer CAD files for your products?
Yes, please visit the Easy Spec on our website.
Installation, Modification, Finishing & Maintenance
Installation & Modification
How do I install a Therma-Tru entry or patio door system?
View our installation instructions and videos.
Can I cut the height of my door?
No. We do not recommend making on-site modifications.
Can I have a storm door?
Yes. However, Therma-Tru is not responsible for any failure of, or any damage caused to, the storm door or any damage caused to your Therma-Tru door as a result of the storm door.
Can I hang a window treatment, such as blinds or curtains, or add a door knocker on my door?
No. We do not recommend drilling into the door. However, if you choose to use an exterior window treatment or a door knocker, you will need to attach the window treatment or door knocker with a pass-through bolt and a finish ring or washer. As an alternative, Therma-Tru offers internal blind options. Check with your local Therma-Tru dealer for product availability.
Can a Therma-Tru door be modified by adding a pet door, mail slot, kickplate or peepsite?
No, we do not recommend drilling into the door. However, if you choose to use an option listed above, follow the manufacturer’s instructions found on the product along with these tips to help protect the integrity of the door:
- For a peepsite, pet door, or a mail slot – Use a product that contains an inner sleeve.
- For a kickplate – To protect the integrity of the door, fill any pre-drilled holes with sealant prior to application.
Is the outdoor temperature important while staining?
Yes, the temperature is extremely important or else the stain will flake, fade, and have a milky look. Temperature should be between 50 and 90 degrees Fahrenheit and the humidity should be below 80%.
What if the weather is not accommodating to finish the unit, how do I protect the jambs and door?
You can prime or clear topcoat all unfinished wood components within 2 weeks until your weather is more accommodating.
Do I sand the door before staining or before applying a second coat of topcoat?
No, this is not recommended or necessary for the topcoat to adhere.
What is the 'white powder' that has appeared on my door stained with a Therma-Tru finishing kit?
We see this when stain has been applied very heavily (usually to achieve a dark color). There are UV inhibitors in the stain, which will migrate through the topcoat when there is a lot of stain on the door. Wash it off with detergent and water. It may come back one or two more times, but will eventually cease. To prevent in the future, use less stain. Most doors do not require heavy stain coats to achieve dark colors. Reducing the UV inhibitor in the stain will begin reducing the durability of the finishing system.
How do I finish my Smooth Star door?
Priming the Smooth Star door is not necessary. Smooth-Star doors are "paint-grade plus" and should only be painted. After cleaning, paint the door using a high quality exterior grade acrylic latex paint. Be watchful of paints with major ingredients like "vinyl polymers" or "polyvinyl acetate" or that are labeled "interior/exterior" in many cases they do not adhere well to Smooth-Star.
Can I order prefinished doors?
Yes. Ask your dealer for more information on the prefinished styles that are available through their distributors.
How do I obtain stain?
Stain can be bought through your local Therma-Tru dealer, by calling 1-877-99-STAIN, or online by placing an order on our website.
Do I have to take the door off its hinges before finishing?
No. The weatherstripping can be pulled out of the jambs, so it can be closed and locked during the drying period. Weatherstripping can be pushed back into the jambs after topcoat has dried.
How much will one kit do?
One kit will handle a single door unit with sidelites, a double door unit or an 8' door unit, inside and out.
What does the Therma-Tru stain kit include?
Our stain kit includes everything you need to finish the inside and outside of a complete double door unit, an 8’ door unit, or a single door with two sidelites. It contains stain, topcoat, several brushes, rags, gloves, mineral spirits, stir sticks and two skin samples.
What do I use to clean the door with?
Using a clean, dry rag, clean the entire surface with either the provided mineral spirits or an all-purpose cleaner such as Top Job, Mr. Clean or Pine Sol. Rinse soap off thoroughly. Allow to dry completely.
Which Therma-Tru doors can be stained?
Classic-Craft and Fiber-Classic doors.
What stain should be used on Therma-Tru Classic-Craft or Fiber-Classic fiberglass doors?
We recommend the Therma-Tru stain kit. However if you wish to use a different kit, we recommend an oil based stain with a water based top coat. Be sure to finish all exposed sides, edges and ends of the door.
Do I have to prime Classic-Craft or Fiber-Classic doors before staining?
Priming is not necessary or recommended unless you are painting your door. For best adhesion, we recommend priming the door with an alkyd-based or acrylic-based primer before painting. The doors can be primed and painted with an exterior grade high quality acrylic latex paint. Be sure to finish all exposed sides, edges and ends of the door.
My wood jambs are clear and I want to stain them. Do I do anything different?
You could purchase a can of wood sealer or wood conditioner and apply it to the jambs to limit the penetration of the stain. The stain is a heavily pigmented stain and could stain the jambs darker if you do not apply a sealer or use the mineral spirits first.
Can I mix stain colors?
Yes, as long as you are mixing Therma-Tru stain with Therma-Tru stain. The stain can be tinted with any "universal" tint to achieve a certain color.
How can I get a high-gloss finish?
Apply 3-5 coats of the Therma-Tru topcoat to achieve a high-gloss finish. Let each layer dry 4 hours before applying the next layer.
What paint should I use on the Classic-Craft or Fiber-Classic door?
These doors should be primed and painted with a high quality acrylic, alkyd or oil-based exterior house paint. Primer and paint should be produced by the same manufacturer and be made to work together.
Can I stain my Smooth-Star door?
No, Smooth-Star doors are "paint-grade plus" and can only be painted. After cleaning, paint with a high quality exterior grade latex or acrylic house paint.
Do I have to prime my Smooth-Star door?
No, it is not necessary to prime the door, but if your door has a doorlite in it, then the molding around the glass should be primed with an acrylic or alkyd primer. Wipe the frame with a clean cloth first, then prime and paint.
How do I repair nicks and scratches or scuffs in the stained finish on my door?
Clean area first with mineral spirits or an all-purpose cleaner. Then, use a small artist brush or cotton swab to apply stain to the nicks or scratches. Carefully wipe or brush off excess stain, let dry and then apply a thin coat of the topcoat over the repaired area. Refer to the finishing instructions under "Repairs". Also, there are a variety of “touch-up markers” or repair pencils that repair scratches or nicks in finishes on fine wood furniture. These do a nice job too.
How do I strip a fiberglass door to restain/repaint it?
To strip our fiberglass doors of paints, stains or topcoats, use a methylene chloride-based stripper. We recommend Savogran® SuperStrip®, Savogran® Kutzit®, or Dad’s Easy Spray® Paint, Stain & Varnish Remover. Do not leave stripper on the door any longer than 2-3 minutes. You may use a nylon bristle brush to remove any stubborn residue. Wipe the door clean then thoroughly wash the door with a mild soap and water. Make sure the door is completely dry before refinishing.
The stripper says to not use it on fiberglass. Can I use it?
Fiberglass doors manufactured by Therma-Tru are made from a fiberglass material that you can safely use the recommended strippers on. Follow our finishing instructions for stripping.
Can I shut my door if the stain is still wet?
The weather-stripping can be pulled out of the jambs, so it can be closed and locked during the drying period. Weather-stripping can be pushed back into the jambs after topcoat has dried and cured.
How do I remove any excess glazing from around the lite frame?
Please see our website for a video on step by step instructions.

Can I place a tint on the glass in my door?
Any alteration or application of any aftermarket films, coatings, tints or other similar products not originally supplied by Therma-Tru will void the glass limited warranty.
Why is there condensation on the glass in my door?
Condensation, or "sweating", occurs naturally in the home, caused by excessive humidity, or invisible water vapor, in the air. When this harmless water vapor comes in contact with a surface which is at a cooler temperature, such as windows or doorglass, the vapor turns to visible droplets of moisture. The energy-efficient glass units in Therma-Tru door systems are constructed to keep the glass as warm as possible, reducing condensation build-up. However, there is no such thing as a condensation-free window or doorglass in high-humidity conditions.
