Procure Group Ltd investigates damp, mould and condensation in Watford property — Victorian and Edwardian terraces, interwar suburbs, purpose-built and converted flats and recent town-centre development.



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.
Watford has a dense mix of housing: extensive Victorian and Edwardian terraces around the town centre and Nascot, large interwar suburbs, and a significant number of purpose-built and converted flats, many of them privately rented. Flats bring their own moisture questions — shared construction, limited external wall area, communal extract systems and neighbouring occupancy all affect what happens inside a particular dwelling.
Because so much of the stock is rented or leasehold, a large share of our Watford work involves establishing responsibility as well as cause: whether moisture originates in the demised property, in a neighbouring flat, or in the common parts.
The older terraced streets bring the more familiar questions of solid-wall construction, subfloor airflow, external ground levels and the condition of rainwater goods.
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.
Online tools
Answer a few simple questions, upload photographs and receive an initial summary of possible causes and the type of survey that may be appropriate.
Upload an existing damp report, building survey, RICS report or property inspection document for an initial AI-assisted summary and recommended next steps.
Send us the details and photographs of the problem and our team will price the work and put it in writing.
Regional project example
We do not have a published project in Watford yet, so this example is from elsewhere in the area we cover. We will not present work as local when it is not.

Questions
It can. Escapes of water, failed seals, poorly maintained communal risers and condensation in adjoining dwellings all show up next door. The investigation considers the wider building rather than only the room where the stain is visible.
Yes. We report to property owners, freeholders and leaseholders, and the portal gives everyone involved a single documented record of the findings and the works.
Yes, along with the wider WD districts. We work across Hertfordshire but do not operate inside Greater London.
Pre-1919 terraces in Watford were typically built without a damp-proof course, or with a slate or lime-mortar course that has since deteriorated. Solid brick walls in these properties absorb ground moisture readily, and where air bricks have become blocked or external ground levels have been raised over the decades, the problem is often compounded. An inspection will confirm whether rising damp is the actual cause, as condensation and hygroscopic salts can produce very similar symptoms.
Newly applied render can trap existing moisture within the wall rather than resolving the underlying cause. If the render is cement-based and applied over a wall that was already damp, or if it bridges the original damp-proof course, water can be deflected inward rather than allowed to evaporate. A survey will examine render condition, wall construction and any bridging of existing damp-proof measures before an appropriate remedial approach is recommended.
