What we investigate

Damp and mould concerns we investigate in St Albans

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, wardrobe 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.

Restricted air movement and cold surfaces

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

Below-ground wall moisture

Damp, salting or water ingress at or just below external ground level.

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.

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

Damp investigations

A structured investigation to establish the likely cause of dampness before any remedial work is recommended.

Damp

Rising damp assessments

Careful assessment of low-level dampness, which is frequently caused by something other than rising damp.

Damp

Penetrating damp investigations

Investigation of moisture entering through walls, roofs, openings and rainwater goods.

Surveys

Specialist damp surveys

Mould & condensation

Condensation control

Assessment of moisture production, ventilation, heating and insulation to reduce surface condensation.

Mould & condensation

Mould remediation

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

Timber preservation

Assessment and treatment of structural timbers affected by moisture, decay or insect attack.

Timber

Woodworm investigations and treatment

Establishing whether insect activity is current before recommending any treatment.

Timber

Wet rot investigation and repairs

Identifying and repairing timber decay caused by sustained high moisture content.

Timber

Dry rot investigations

Careful investigation of suspected dry rot, which can extend beyond visibly damp timber.

Repairs & finishes

Damp-resistant plastering

Replastering specifications appropriate to walls affected by dampness or salt contamination.

Repairs & finishes

External damp-related repairs

Repairs to the external fabric that address the source of moisture entry.

Repairs & finishes

Water-damage reinstatement

Drying, repair and reinstatement following leaks, escapes of water or flooding.

Local property context

Property and moisture in St Albans

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

What happens during your survey in St Albans

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, building 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, airflow, 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.

Questions

Frequently asked questions — St Albans

Is injected damp proofing appropriate for a period house?

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.

Can you work on a listed building?

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.

What should a damp report include?

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.

St Albans has a lot of Victorian and Edwardian terraces — are they particularly prone to rising damp?

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.
