Causes of Damp

With over 172 days of rain a year, damp proofing in North Yorkshire is essential. There are numerous ways that water can enter your building and cause damp, some of the most common are:

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

Without proper damp proofing, water can enter your home and begin to spread through walls via capillary action. This damp in your home can cause wood rot, attract woodworm and cause a whole host of other costly damage.

Signs of Damp

Rising damp, the most common type of damp in York, is the process of water entering a home by soaking in an upward direction, through brickwork and mortar. Certain building materials are porous, such as brickwork and stonework, which means that they can absorb moisture, which transfers to other nearby building materials via capillary action. Consequently, when rising damp occurs, it can damage large areas of your property.

Penetrating damp occurs when water enters a building by passing horizontally through building materials. It’s most common in basements as the earth surrounding the external walls always holds some degree of moisture. As this moisture can spread throughout your property, it’s important to get this treated immediately. 

The key signs of damp are:

  • Flaking or blistering plaster
  • Mould and black mould spots
  • Cracks in walls
  • Salt deposits visible on walls

Damp Treatments we use

Allerton ALL DAMP DPC Gun
CHEMICAL DAMP PROOF COURSE

Our chemical damp proof course, exclusive to the ALLDAMP range, can be used retrospectively on properties throughout York. This intelligent damp treatment adds a water-resistant quality to the mortar between your property’s brickwork.

We’re so confident in its damp proofing ability that, when installed by Allerton, we can guarantee its effectiveness for 20 years.

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, prventing 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

Perfect for all projects, including waterproofing basements, the ALLDAMP damp proofing membrane creates a barrier and cavity between the existing brickwork and wall surface. The membrane can be plastered over and works effectively to prevent future damp penetration.

FOUND DAMP?

Both rising and penetrating damp can damage structure’s integrity and, if left untreated, cause extremely costly repairs. Condensation and the mould which forms because of it, can also threaten your health.

Dry and wet rot damage woodwork, floors, and timber in properties, causing floors to collapse if left untreated. They make the building dangerous and can lead to expensive repairs in the future.

If you see any signs of damp, get in touch with a damp proofing expert immediately. The sooner you speak to a damp proofing specialist the sooner you’ll have peace of mind that your building’s structure has not been compromised.

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.
