Why buy DOORBRIM products?

Our awnings are superior to competitor metal flashings in several aspects. Unlike our competitors products made of steel,  DOORBRIM awnings will never rust and will last a lifetime. A huge difference is the integrated front gutter. DOORBRIM awnings project a full 7 1/2″ away from the wall compared to small metal drip edges without front gutters. The front gutter will not only prevent dripping but will direct water out and away from building structures. Extend the life of your doors, windows and hardware with DOORBRIM awnings.  A great alternative against expensive repairs and replacement, our awnings are easily installed with minimum tools. I am a prior property maintenance manager and realize firsthand the value in spending wisely. However, it will be prudent to consider that our products will also protect & preserve your doors, jambs & hardware for many additional years. You don’t have to wait for the inevitable deterioration and leaks from normal weather and UV rays. A DOORBRIM rain diverter is cheap insurance compared to a future repair and/or replacement.

    DOORBRIM Leak Checklist Tool?

  • Are there any penetrations above the opening that could be the source of leaks like a wall vent or louver for attic circulation? 
  • Look for cracks in the stucco above openings. Route out all cracks should be with a grinder and caulk. Elastomeric paint may also be a solution but not in all cases.
  • Broken, clogged or leaking gutters and roof flashing may excessively funnel rain water over doors and windows.
  • Check siding trim for faulty old or cracked caulking.  There are many grades of caulking and most do not last forever. 100% silicone is not affected by the sun’s degrading UV rays.
  • Windows and doors should have flashing installed before siding as an added protection rather than relying solely on the trim to divert water.
  • Check to see if the door is installed in a recess lower than the finish floor? Check to see if the recess sloped outwards correctly or incorrectly inwards?
  • Look for negative pitched concrete slabs and decking that funnel water under and around thresholds and jambs. You should not rely on caulking as the sole defense in these areas. Caulking typically fails here in time.
