Procure Group Ltd investigates damp, mould and condensation across Corby, working for homeowners, property owners throughout the town's estates and newer developments.



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.
Corby expanded dramatically as a designated new town from the 1950s onwards, and a large share of its housing dates from that programme. Housing of this era typically has early cavity walls, larger glazed areas and airflow provision designed for a very different heating regime — which is precisely why condensation and cold-bridge mould are such frequent findings once windows and insulation have been upgraded.
Since the 2000s the town has seen substantial new development, bringing much more airtight construction and reliance on mechanical extraction. When those systems underperform or are switched off, humidity rises quickly, and the resulting mould is often mistaken for a structural damp problem.
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 Corby 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 depends on the cause, which is exactly why an evidence-led investigation helps. Where mould results from a building defect or inadequate airflow provision, that is a property matter; where it results from how a home is heated and used, practical guidance usually resolves it. Our reports set out the evidence rather than apportioning blame.
Yes. We provide documented damp and mould investigations with photographic evidence and clear recommendations, which supports relevant housing hazard assessment and applicable damp-and-mould response obligations. We do not guarantee legal compliance — that depends on your own processes.
Well-specified airflow is designed to remove moisture without wasting heat, and we take running costs into account when recommending a system. Living in a mould-free home usually costs less than repeatedly redecorating.
Much of the NN17 and NN18 housing stock was built rapidly during the mid-twentieth century to house steelworkers, often using non-traditional construction methods and materials that are now ageing. Some of these builds have limited cavity detailing or use dense renders that trap moisture. Whether that translates into rising damp, penetrating damp or interstitial condensation depends on the individual property and can only be confirmed through a thorough on-site inspection of the walls, floors and roof junction details.
Condensation typically presents as mould on cold surfaces such as window reveals, external corners and north-facing walls, and often fluctuates with the seasons. A structural defect – such as a failed damp-proof course or penetrating damp through a wall – tends to produce localised tide marks, salting or persistent dampness that does not improve with airflow. The two can appear similar, which is why a diagnostic inspection using calibrated moisture meters and a thermal assessment is the reliable way to distinguish between them before any remedial work is specified.
