Pretty please can anyone reccomend a damp proofing company near Stratford on Avon. Unfortunately it's still an open door (me), rub hands (them), 'Oh look grey haired female..this will be easy!', world!
'Damp' could cover a multitude of sins/problems. Is it a chemical damp proof course in the [ancient?] stone walls that were built before the modern damp proof membrane was invented? Is it a black mould infestation or similar on an internal wall [often where the outside of the wall is in an exposed position and the cold/moisture can seep through older walls]? Are the gutters/drainpipes sound/secure, or is water leaking into the property, causing fungus growth, a precursor to Dry Rot? Is the property floor at least 15cm higher than the outside soil/paving, otherwise rain water can bounce back up and cause damp, especially if there is no original damp proof course in the walls
The best option [so not the cheapest] is to get a Damp Check Survey from a national contractor e.g. Peter Cox that will identify the likely cause of the problem, and the quote will include a 20 year guarantee [might still be possible to get a 30 year guarantee but that will be more expensive] and will be a comprehensive service, laying dust sheets, plastic protectors, moving furniture etc [so that's Day 1 of the contract price spent] and a daily hoovering up of debris before leaving site. Then ask around/look at CheckaTrade etc locally for a local specialist Damp Proof Contractor and get references on the work. If you can live with a less pretty service [i.e. hoover up the dust and debris at the end of each day, and shift as much of your furniture as possible etc], so that you are paying for the specialist work of hacking off plaster, replastering after chemical treatment of any Rot and installation of new pre-treated timbers], you may well be able to save a lot of money.
Our Peter Cox quote was £18,000 in 2017; the 'do your own cleaning up' alternative, covering the same area of work, and same treatment, with nationally recognised chemical treatment, was £13,500. and the contractor has been back twice without charge to look at what turned out to be dead dry rot within about 18 inches of where the original treatment stopped! [the Peter Cox quote carried a warning that if further damp problems occurred outside the treated area, even by a few inches, the extra work would be chargeable. This is acceptable, because the rot is cut back until sound timber is found and then new half joists are spliced onto the original joists and old/new timbers chemically sprayed. The only viable alternative is to demloish the property, rip out every piece of timber and rebuild with brand new full joists etc, and the bill will be well into 6 figures!
Lastly, dry rot/damp is not covered by house
insurance; insurers take the view that the problem arises from lack of maintenance ...
