Damp, Mould and Timber Specialists Serving Stevenage

Procure Group Ltd investigates damp, mould, condensation and timber decay across Stevenage — the Old Town, the new town neighbourhoods and the more recent development around the town's edges.

Professional damp investigations, mould assessments, condensation advice and evidence-led remedial solutions for homeowners, landlords and property professionals in Stevenage.

What we investigate

Damp and mould concerns we investigate in Stevenage

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.

Damp patches and tide marks

Staining at low level or around a specific point on a wall or ceiling.

Mould growth

Black, green or grey growth on walls, ceilings, sealant, window reveals or behind furniture.

Musty odours

A persistent smell, often in a cupboard, cellar or unused room, sometimes before anything is visible.

Peeling paint and damaged plaster

Blistering, salting, crumbling plaster or wallpaper lifting away from the wall.

Condensation on windows

Water on glass and frames in the morning, and mould appearing on cold surfaces.

Water penetration

Damp appearing during or after rain, frequently linked to rainwater goods or pointing.

Suspected rising damp

Low-level dampness that may be rising damp, or may be one of several other causes.

Timber decay and woodworm

Soft or crumbling timber, fungal growth, exit holes or springy floors.

Leaks and escapes of water

Plumbing, heating or drainage leaks that show up some distance from the source.

Poor ventilation and cold surfaces

Rooms that feel humid, cold spots at reveals and lintels, and extract fans that do not clear steam.

Basement and cellar moisture

Damp, standing water or high humidity in below-ground space.

We do not diagnose rising damp from photographs or from a single meter reading, and we do not assume that every damp problem needs chemical damp proofing. A great many do not.

Local property context

Property and moisture in Stevenage

Different construction types behave differently when they get wet, so the approach is matched to the building in front of us.

Stevenage was the first town designated under the New Towns Act, and the great majority of its housing was built from the 1950s to the 1970s in planned neighbourhoods such as Bedwell, Shephall, Chells and Pin Green. That housing was designed around open-flued heating and generous incidental ventilation. Decades of window replacement, draught-proofing and insulation upgrades have changed the moisture balance in these homes considerably, and condensation is the predictable result where extract ventilation has not kept pace.

The Old Town along the High Street retains older brick and timber-framed buildings where the considerations are quite different — maintenance history, ground levels, past remedial work and the suitability of previous treatments.

Our approach

What happens during your survey in Stevenage

The purpose of a survey is to identify the underlying cause of the moisture, not to justify a particular treatment.

  1. 1Your enquiryYou tell us what you are seeing, where and when. Photographs help.
  2. 2Understanding the symptomsWe ask about the pattern — after rain, in cold weather, worse in one room.
  3. 3Reviewing what you already haveExisting reports, homebuyer surveys or previous quotations are read before the visit.
  4. 4Choosing the right surveyThe survey type is matched to the problem rather than sold as a package.
  5. 5Inspecting the propertyInternal and external inspection, moisture and psychrometric readings, photographs.
  6. 6Considering moisture sourcesConstruction, ground levels, rainwater goods, ventilation, heating and occupancy.
  7. 7Clear written findingsWhat was found, what it means, and where the evidence is inconclusive.
  8. 8Recommended next stepsIn priority order, with the reasoning behind each recommendation.
  9. 9Quoting only where work is neededItemised, with assumptions and exclusions stated.
  10. 10Portal access throughoutReports, quotations, project stages and documents in one place.
  11. 11Aftercare and guidanceDrying and decoration advice, maintenance instructions and guarantee details.

Regional project example

A project from elsewhere in our region

We do not have a published project in Stevenage yet, so this example is from elsewhere in the area we cover. We will not present work as local when it is not.

· Bedford

Victorian terrace, Bedford

Reported problem
Recurring damp to a chimney breast had previously been treated internally twice. Investigation identified defective flashing and a blocked hopper as the moisture source.
Agreed approach
External repairs were carried out, the wall was allowed to dry and the internal finish was replastered only where it had genuinely failed.

Questions

Frequently asked questions — Stevenage

Why does mould appear around my window reveals and in corners?

Those are the coldest surfaces in a room, particularly where there is a cold bridge at a reveal or a lintel. Warm, moisture-laden air condenses there first. It is a classic condensation pattern and it responds to ventilation, insulation and heating measures rather than damp proofing.

Do you treat woodworm in Stevenage?

Yes. We first establish whether the activity is current and what species is involved, because treatment is only warranted where there is active infestation — and because dampness in the timber is often the underlying reason it became vulnerable.

Can I get a cost before booking?

Yes. Request an Estimate and our team will price the work from your details and photographs rather than an automatic calculator; the final figure depends on what the inspection finds, along with size, access and specification.
