Trusted Installer Of The StrongJamb System

In 2010 Greg Pollard, owner of ProSpeed, invented, then field tested for 5 years, our trademarked product, StrongJamb. StrongJamb gives you an opportunity to make improvements for doors that no other jamb system can provide. Reuse, Replace, Repurpose, Restore, and Replicate any door for residential construction. StrongJamb accommodates the technical entry systems for new construction and confidently applies new technology, green sourcing, and current weatherization to even the oldest historical doors. StrongJamb has the added bonus of putting commercial grade security in your home that's not ugly! It is not an attachment, but is built-in, making every door a physical barrier. 3/16" steel plates at the lock set, laminated substrate give 24 hour security at a one time cost. StrongJamb is the strongest defense at the weakest link in home security.
