## In customers' own words
_Verbatim quotes from this trader's public reviews, each attributed to its source:_
> "EnviroVent conducted a service of my PIVS system and bathroom Cyclone fan. Arranging the call was easy, with the company keeping me informed, with useful reminders of their attendance. The service was excellent, carried out by first class technicians, with some warranty work and upgrades done without any fuss or even having to ask. I would strongly recommend EnviroVent to anyone. In fact I did just this to my neighbour, who then went ahead with his own installation. Thank you EnviroVent. Great job, great service, great professionals. Mike C is particularly worthy of thanks, since first contact"

> "Extremely great. This is the second time I have used this company. The first time was far more complex than this time. Fast, efficient and effective for damp and mould due to lack of ventilation in tenanted properties - highly recommend. The investment is worth it to eradicate the problem."

> "Prompt diagnosis and efficient installation. Very happy with the result."

## Before you hire a damp proofing / waterproofing
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- Get an INDEPENDENT damp survey — not a free one from the firm that wants to sell you the treatment. A free survey has every incentive to diagnose expensive 'rising damp', when the problem is often condensation, a leak, or high ground level that needs no chemical injection.
- Insist they identify and fix the underlying CAUSE — a leak, blocked airbricks, poor ventilation, failed pointing — before agreeing to an injected damp-proof course, and ask them to explain why simpler fixes won't work.
- Get the diagnosis and an itemised quote in writing, and be wary of pressure to sign on the spot for a long 'guarantee' that is only worth anything while that firm is still trading.
- Look for a surveyor or contractor accredited by the Property Care Association (PCA) — the recognised UK body for damp and timber — and prefer an independent, CSRT-qualified surveyor for the diagnosis itself.
- Look for consistent reviews across several named sources, not one polished profile.
