Causes of Damp

In the Sheffield area, damp often occurs in older buildings (as defects will occur as time passes) and in new build properties which have been built incorrectly. Typical causes of damp include: 

  • The absence of a working damp proof course
  • High external ground levels
  • Leaking pipework
  • Missing roof tiles
  • Cracked mortar or brickwork

If your property isn’t damp proofed, water can enter your home and affect numerous areas. When damp enters a home in this way, it can cause a wide range of costly repair issues.

Signs of Damp

There are three main types of damp, rising damp, penetrating damp and condensation. 

Rising damp is caused when moisture is absorbed upwards through your walls from the ground. Penetrative damp occurs when water penetrates your walls horizontally; this can be due to plumbing issues, poorly fitted windows or roofing defects. Condensation problems arise when your home is not properly ventilated and/or insulated. 

Key signs of damp are:

  • Flaking or blistering plaster on walls
  • Mould, such as black or green mould patches
  • Cracks in walls
  • Salt deposits on the surface of walls

Damp Treatments we use

Allerton ALL DAMP DPC Gun
CHEMICAL DAMP PROOF COURSE

A retrofit chemical damp proof course, exclusive to the ALLDAMP product range. The chemical adds a water-resistant quality to the mortar between a property’s brickwork, preventing rising damp occurring in future. When installed by Allerton this product can be guaranteed for 20 years, giving you long-term peace of mind.

RENDER ADDITIVE

 A specially-formulated render additive which acts as a water inhibitor and plasticiser. When carrying out plastering inside homes, our staff use ALLDAMP Render Additive, turning their plasterwork into a damp proof barrier to future water ingress. 

ALLDAMP Render Additive is used in most Allerton repair projects. With this system, homeowners can redecorate and furnish with the confidence that damp will not return in future.

DAMP PROOFING MEMBRANE

A specially-designed wall covering, which creates a damp proof surface over which plasterboard and plaster can be applied. The ALLDAMP damp proofing membrane creates a damp proof barrier and cavity between the existing brickwork and wall surface, preventing future damp penetration.

ALLDAMP Damp Proofing Membrane is an incredibly versatile product which is suitable for use above and below ground. It is our go-to product for carrying out basement waterproofing projects.

FOUND DAMP?

In Sheffield there are homes, commercial properties and buildings from many decades, spanning hundreds of years. All require specialist and unique care in order to prevent their gradual deterioration.

Both rising and penetrating damp can eventually damage the structural integrity of your home; condensation and mould can threaten your health.

Damp can lead to Woodworm, Dry Rot and Wet Rot in timber; this eventually weakens timber floors and can cause their collapse. This makes the building dangerous and can lead to expensive repairs in the future.

If you have any signs of damp, it’s best to deal with it as soon as possible, so please get in touch.

Reviews

Allerton were exceptional at keeping in touch with me from the first phone call, right through to the quality control visit after work was completed. All the team were friendly, professional and ensured the disruption to the rest of my home whilst works were ongoing were kept to a minimum. They cleaned the site daily and ensured we were happy with progress throughout the project. Pleasure to work with.

Allerton provided a highly professional service from start to finish and did a quality job. Their expert visited the property and explained the proposed solution to condensation in a clear way. The information provided on e-mail was clear and comprehensive with an efficient e-payment system.

Allerton’s carried out damp treatment work on our property. They were quick, efficient and tidy. Changes to our requirements were dealt with well and nothing was too much trouble. Indeed we appreciated the hassle free way we were dealt with, the fixed quote with no “hidden extras” or later additional costs that we weren’t expecting. A great service and good work.

Very professional and reliable company to deal with, after being let down by others not turning up, it was refreshing to deal with Allerton, from arriving to survey and quote through to the finished job. The team of two who carried out the work, were very professional, polite and friendly and did a great job of the work itself and cleaning up afterwards.

Me and my partner cannot recommend Allerton enough. From day 1 they were professional and the level of communication from the start of the job to the final day was exceptional. Constant messages asking questions and for reassurance. A great Company for all damp proofing works but also for the additional works as well, like plastering, boarding, electrics etc.
