Another well deserved recommendation for JKA damp proofing! An excellent job done on our front bay window. To help sort a damp issue in our bedroom they did a new damp course but also a sorted out a windowsill that was in dire need of attention but now looks fantastic! Jonathan's professionalism, expertise and attention to detail (even down to the texture of the final look of the windowsill to match the victorian property) was second to none. We're very happy with the work and would highly recommend him if anyone needs similar work doing in East Dulwich!
