Retrofit Sump System
A radon sump is the term given to a small void created in the hardcore beneath the building, this will be approxmately the size of a builder’s bucket. This void creates an area of low pressure which soil gas will now be towards as a new path of least resistance.
Pipework is then taken from the sump to safely exhaust the gas away from the building. A fan is fitted to the pipework to ensure that the gas is being moved away from the sump. The exhaust pipe discharges well away from any doors or windows, usually above the level of the eaves.
Luke and team installed a PIV loft unit for me. They were reliable,
honest, did a great job and tidied up afterwards. Really pleased with
the work and would be happy to recommend.

After years of constant mould problems occurring in my bedrooms and streaming windows every morning I decided to contact Luke at LHR
contractors. He recommended a PIV whole house ventilation system and mould treatment in both bedrooms. As a result I have no mould issues
anymore, streaming windows have gone and my asthma has calmed down. Luke was very clean, tidy and courteous. I couldn't recommend LHR contractors highly enough, one happy customer!

LHR installed a PIV in the loft space in my 2 bed house to reduce the
condensation problems, they done a neat and tidy job! thank you

Luke was very professional and knowledgable, he installed a new bathroom fan and a PIV unit in the loft. I'm very happy with the works completed and my ongoing condensation issue has finally been dealt with.

For years I've had really bad mould problems in my bathroom, I used
every bleach I can think of removing the mould on the ceiling to no
avail, LHR installed a bathroom fan and completed a full mould
treatment and so happy and relieved. My bathroom looks how it should and
looks fresh and clean! Thank you guys!

The bathroom and kitchen fans have made a tremendous difference to my house, no more mould! couldn't recommend LHR enough.
