There are many reasons for installing a new door or entryway system. Whether you are planning on selling your home, or plan to continue residing in it, a new door can increase your home's value by adding to it's curb appeal and by functioning in a more efficient manner to lower utility costs.
Newer doors often fit better and insulate better than older doors, and while people used to choose wood doors based on their visual appeal, today's doors offer the same beauty as well as being more efficient energy wise.
Key features to consider are energy efficiency, security, and visual appeal. All Iossi Doors are tested and researched to provide the best quality in each category, and we are experienced in the styles of home that each product is well suited to.
See our Getting Started Guide for additional tips.
You may decide to finish your door yourself or you may decide years from now to change the finish on one of our installed doors. PLEASE see the care and maintenance section for information on stripping to refinish.
In either case, we offer One-Day Stain kits, as well as reliable recommendations for paint products.
Following are some of the tips we recommend:
Smooth Star Doors:
Painting Doorlite Frames:
Classic-Craft and Fiber Classic Doors:
To finish Doorlite Frames and Panel Inserts:
To Stain Doors:
All Iossi Door systems and components should be inspected on an annual basis for the following conditions:
Clearcoats and Stains: All exterior finishes are affected by exposure and weathering from the sun, moisture and air pollutants. A simple application of a maintenance coat (topcoat) will renew the projection over the stained surface on Classic-Craft, and Fiber-Classic door slabs. Before top coat fails, reapply fresh topcoat. Clean first with a house hold detergent (mild) and water. Rinse and let dry. Reapply the topcoat approximately every 3 - 5 years or when gloss fades. Fading will vary.
Paint on Classic Craft or Fiber Classic Doors: For fading, cracking, splitting, etc., of Classic-Craft or Fiber-Classic doors, stripping and refinishing may be required.
Paint on Smooth-Star Doors: For cracking, splitting or deteriorating paint finishes on Smooth-Star doors, lightly sand surface of door and touch up to match overall finish.
Special Note for Outswing Door Systems: Swing-out doors must have all edges- sides, tops and bottom - finished. Inspect and maintain these edges regularly as all other surfaces.
Weather-stripping: If the weather-stripping fails to perform (i.e., snot sealing the door system properly, cracking, tearing, etc.) the weather-strip needs to be replaced. Remove the existing weather-stripping and replace.
Door Bottom and Gaskets: If the door bottom gasket fails to perform (i.e., splitting, cracking, etc.), the door bottom needs to be replaced with a new door bottom. If the sill gaskets on outswing sills fails to perform (i.e., splitting, cracking, etc.), the sill gasket needs to be replaced. Pull the existing gasket and replace the gasketing for proper functioning of the sill.
Riser for Adjustable Sills: If the riser for an adjustable sill fails to perform (i.e., splitting, cracking, etc.), the riser needs to be replaced. Remove the existing riser and replace.
Vinyl Thresholds: If the vinyl threshold fails to perform (i.e., splitting, cracking etc.), the vinyl threshold needs to be replaced. Remove the existing threshold and replace.
Corner Seal Pads: If pads are torn or missing, replace.
Sealing/Resealing Areas: If a caulk seal fails to perform (i.e., water leakage) remove existing seal and reseal areas.
