Clarke Basements and their representative, Roy Warren, have demonstrated quick, professional service when responding to my e-mail request for an estimate to waterproof the crawl space under our 1930's rental addition. My request was made mid December and mid January the work is complete. Before Roy came to do the estimate the company sent us a book about Crawl Space Science explaining issues with conventional crawl space construction and the science behind their solution. This gesture was well beyond my expectations.
As an architect, I have had my eye on the "Basement Systems" crawl space strategy for numerous years as it challenges the conventional approach of ventilating crawl spaces and promotes sealing the crawl space from the exterior instead. Our crawl space was ventilated and it suffered all the typical/ chronic problems associated crawl spaces under dwellings: ruined insulation, moisture and mold due to condensation.
The installation of the encapsulation system has been done with good quality materials and equipment by an efficient hardworking crew. They even did a thorough post completion clean up. Roy came back to do an inspection and personally fine tuned the new Smart Sump. Now we have a dry, clean, warm crawl space. According to our tenants, their home feels warm, dry and comfortable ... just in time for their new baby who is scheduled to arrive any day now.
