Commercial damp proofing is the same diagnosis, rising damp, rain through the wall, or condensation, carried out on shops, offices, and managed housing. It is for non-domestic buildings in England, Scotland, and Wales and is specified around opening hours. Send the quote form or WhatsApp with the building type.
Commercial Damp Proofing
Owners and managers of shops, offices, blocks, and commercial units. The building is still diagnosed. A shop window leak is not quoted as a basement tanking job.
Access, trading hours, and shared structure. Party walls, basements under a sales floor, and plant rooms are surveyed as they are, not as a living room.
You get the cause, the work excluded, and a quote a manager can compare. The 30-year guarantee applies to the treatment that quote names.
We do not run a facilities contract, clean offices, or treat a process leak from plant as if it were rising damp. A burst pipe is still a plumber.
Commercial Damp Proofing
Storage under a shop is often below ground. It is quoted as basement work if water pressure is the problem.
Failed flashings, canopies, and pavements bridging the course are common on street properties. They are outside repairs or bridging, not an automatic injection.
Unheated stairwells grow condensation mould. The specification is ventilation and heat, which has to be acceptable to the building manager.
A local wet wall next to a cistern or a roof plant room is checked as a leak first.
A shop or a managed building needs a time the unit can be worked in. That is agreed before the survey date.
Damp in the shop may not be the same cause as damp in the flat above. Each floor is checked on its own.
Trading hours and protected stock are part of the survey brief, not a surprise on the day.
Trading hours and protected stock are part of the survey brief, not a surprise on the day.
Rising damp, rain, condensation, and leaks are separated.
The quote says what is opened, what is protected, and what you need to clear.
Injection, outside repair, ventilation, basement work, or timber, as the survey decided.
The cause, the work done, and the drying limit are recorded for your file.
The treatment named in the written quote carries a 30-year guarantee.
Commercial quotes move with access, the area that has to be done outside trading hours, and the same building factors as a house: metres of wall, plaster, basements, or rainwater defects. A day rate with no diagnosis is not a quote we issue.
Questions that decide whether this is the right job.
Yes, when access is agreed. Tell us the hours on the form. We will not assume we can close the floor.
The damp types are the same. Access, shared structure, and the paperwork are what change.
You get a written cause and a quote that names the work. That is not a RICS report for a purchase.
Each building is surveyed. A portfolio is a set of surveys, not one price copied across addresses.
Tell us the floor, whether it follows rain, and the postcode. The quote follows the survey.
