ISO-Therm internal wall insulation to an art gallery
- Agreed approach
- ISO-Therm internal wall insulation installed throughout the gallery, fitted from scaffold and finished ready for decoration.
St Albans has a high concentration of period, listed and conservation-area property. Procure Group Ltd investigates damp and mould in these buildings — and in the city's modern housing — with recommendations proportionate to the evidence and appropriate to the construction.



What we investigate
Any one of these symptoms can have several different causes, and the right remedy depends entirely on which one it is. That is what a survey establishes.
Staining at low level or around a specific point on a wall or ceiling.
Black, green or grey growth on walls, ceilings, sealant, window reveals or behind furniture.
A persistent smell, often in a cupboard, wardrobe or unused room, sometimes before anything is visible.
Blistering, salting, crumbling plaster or wallpaper lifting away from the wall.
Water on glass and frames in the morning, and mould appearing on cold surfaces.
Damp appearing during or after rain, frequently linked to rainwater goods or pointing.
Low-level dampness that may be rising damp, or may be one of several other causes.
Soft or crumbling timber, fungal growth, exit holes or springy floors.
Plumbing, heating or drainage leaks that show up some distance from the source.
Rooms that feel humid, cold spots at reveals and lintels, and extract fans that do not clear steam.
Damp, salting or water ingress at or just below external ground level.
What we are asked for
Each of these is a different problem with a different remedy. Which one applies depends on what the readings and the building show.
An evidence-led investigation of what is making the wall wet, with readings and findings you can act on.
Where a damp-proof course has genuinely failed, the appropriate remedial specification for the wall in question.
Professional remediation of the contamination, and control of the moisture conditions behind it.
Humidity, ventilation and surface temperature measured before any equipment is recommended.
Damp at or just below external ground level investigated, with localised protection where remediation calls for it. We do not install basement or cellar waterproofing.
Services
Each service below links to the full national service page, where the investigation, the treatment options and the circumstances in which it is not appropriate are set out in detail.
Damp
A structured investigation to establish the likely cause of dampness before any remedial work is recommended.
Damp
Careful assessment of low-level dampness, which is frequently caused by something other than rising damp.
Damp
Investigation of moisture entering through walls, roofs, openings and rainwater goods.
Surveys
Mould & condensation
Assessment of moisture production, ventilation, heating and insulation to reduce surface condensation.
Mould & condensation
Treating the mould is only part of the solution. We investigate why it developed in the first place, then remediate the contamination and control the conditions that caused it.
Timber
Assessment and treatment of structural timbers affected by moisture, decay or insect attack.
Timber
Establishing whether insect activity is current before recommending any treatment.
Timber
Identifying and repairing timber decay caused by sustained high moisture content.
Timber
Careful investigation of suspected dry rot, which can extend beyond visibly damp timber.
Repairs & finishes
Replastering specifications appropriate to walls affected by dampness or salt contamination.
Repairs & finishes
Repairs to the external fabric that address the source of moisture entry.
Repairs & finishes
Drying, repair and reinstatement following leaks, escapes of water or flooding.
Repairs & finishes
Insulation of solid walls with careful attention to moisture risk and detailing.

Local property context
Different construction types behave differently when they get wet, so the approach is matched to the building in front of us.
Much of central St Albans and the surrounding streets is Victorian, Georgian or older, a good deal of it within conservation areas or listed. These buildings were constructed to manage moisture by evaporation, and later cement renders, impermeable paints or injected treatments can make a damp problem worse rather than better. Establishing what has already been done to a wall is often as important as measuring it.
The city also contains substantial interwar and post-war suburbs and later development, where the questions shift towards insulation, cold bridging, extract fans and how the property is heated and occupied.
Our approach
The purpose of a survey is to identify the underlying cause of the moisture, not to justify a particular treatment.
Transparent pricing
A Damp Proofing Quote Assessment is £114 plus VAT. The fee can be deducted from the final invoice if eligible remedial works proceed, subject to the agreed terms. Other inspection types are priced according to their scope.
Inspection requirements vary between properties, so larger, more complex or commercial buildings are priced according to their scope. You will be told the fee before the visit is confirmed — there are no charges added afterwards.

Questions
Rarely, and only where rising damp is genuinely confirmed. In older solid-wall buildings the more common findings are penetrating damp from defective rainwater goods or pointing, bridged levels, or condensation on cold surfaces. Injecting a wall in those cases achieves nothing.
Yes, and we will be explicit about where listed building consent is likely to be required. Recommendations for listed and conservation-area property favour breathable, reversible and minimally invasive repairs.
The construction and context of the property, the symptoms reported, the readings taken and where, photographs, the surveyor's conclusion on cause with reasoning, recommended remedial work with priorities, and what further investigation would establish if anything remains inconclusive.
Victorian and Edwardian terraces throughout AL1, AL2 and AL3 were typically built without a modern damp-proof course, or with a slate or bitumen layer that has since deteriorated. Party walls shared between terraces can also allow lateral moisture transfer, complicating diagnosis. Whether rising damp is the true cause of dampness in any particular property is confirmed only after a thorough inspection, which distinguishes it from condensation, penetrating damp or plumbing-related moisture.
