Confidence in the quality of our work

Work Guaranteed!

We offer a 10 year guarantee on all damp proofing works on the areas treated within your property. For instance; if damp rises in the same area then it will be repaired at zero cost to you!

Our guarantees are registered to the property itself so if you decide to sell your property there no need to transfer the guarantee across to the new owners.

A lot of damp proofing firms only do the damp proofing works and not the finishing touches, such as the plastering and making good, leaving the property only half finished and having the hassle of having to find another tradesman to finish the work off. Here at Dryseal Damp Proofing Services we offer the full package working alongside our extremely well recognised sister company; Blaydon Plastering Services to complete the job from beginning to end.

Spotting the signs

Different types of damp

Here are some of the tell tale signs that you may have damp in your property.

  • Lifting or peeling wallpaper
  • A musty, damp smell
  • Dark patches of mould on the walls, floors, ceilings or around windows
  • Rotting or damaged skirting boards
  • A white residue left in walls and floors when soluble salts dissolve
  • Patches of discoloured paint or wallpaper on a wall
  • Walls that are cold to touch

Rising Damp

Rising damp is the name given to the process of external groundwater being drawn up through brickwork by what is known as ‘capillary action’.

If you see moisture at the base of the wall this could be rising damp. Often a ‘tide-mark’ is visible, typically up to 1m above floor level, but occasionally higher. You may also spot salt marks in walls and plaster suffering from rising damp as salts are present in ground water.

In newer houses, there will be a damp-proof course (typically built into a wall at 15cm above ground level) and a damp proof membrane under the floor to prevent water from moving upwards. The two are connected to provide a seal to any water coming into the house. However, many older properties were built without one or either of these forms of protection.

For many homes, these barriers can be damaged, worn away, or compromised by higher external ground levels over time. Without these barriers, damp may start to appear on the walls or floors of your home.

Penetrating Damp

Penetrating damp is normally the result of external defects on the home that allows water to enter the building fabric. Typical property or building external defects that may lead to rainwater penetration include:

  • Defective roof coverings
  • Poorly maintained rainwater system, gutters, drains and downpipes
  • External vegetation affecting the rainwater system and wall surfaces
  • Cracked or defective render or other external coatings
  • Tired mortar joints and defective pointing
  • Broken masonry or permeable brickwork or stone
  • Defective seals around windows and doors

The extent of the problem will be dependent on the type of defect. For example, a leaking downpipe will likely result in a fairly localised problem. However, if the issue is porous brickwork, then the problem will be more widespread and potentially more expensive to fix.


The most common type of damp is condensation. The main signs of condensation are excessive water droplets running down the windows or walls or a dark mould appearing on windows or behind furniture on external walls.

There are a variety of reasons condensation may be causing you problems. Inadequate heating or a lack of ventilation in the property causes the majority of condensation issues.

Services and Treatments

What we provide

Damp Proofing

Most people have had some experience with damp in their homes and it’s never pretty.

Damp can damage your home, your internal decoration is affected and the dampness can be smelled throughout the house. Tell tale signs of damp are crumbling plaster, curling wallpaper, flaking paint and rotting skirting boards.

If your damp problem is not dealt with, it can lead to more serious complications further down the line. It is especially dangerous for young children, the elderly and people who have asthma as reported in the news lately.

There are many modern treatments available; one of the most beneficial is to have damp membrane installed using fixings with a decorative finish applied over the top. Other options include tanking slurrys, renders with admixtures and damp proofing paints.

With so many damp proofing methods and products available, it can be confusing when deciding which option is the best for your situation. We at dryseal are here to help so give us a call for the best advice available

Chemical Injection

Installing a chemical damp proof course is simply the injecting of a silicon based compound in the cavity of a wall through a series of small holes drilled along the base of a wall that is suffering from rising damp.

Contrary to common belief, a chemical damp proof course does not create an impenetrable physical barrier. Instead, chemical damp proofing is a method of lining the pores along a stretch of a brick wall with a water repellent resin. The resin lined pores neutralise the attraction of the brick work particles to the water molecules, thus reducing adhesion to a level suitable to the cohesive force of the liquid.

The damp-proof injection method is one of the main methods of treating rising damp in houses. Here at Dryseal we only use BBA approved creams to meet the necessary criteria required

Insulated Renders

Here at Dryseal we offer a full range of different Insulated coloured renders including:

Ewi - Why choose Ewi render?


Insulating your home is one of the most effective ways to retain heat and reduce your energy bills. This is because many homes, both old and new, are not insulated as well as they could be.

The majority of the heat loss is through your walls making ewi the way to go to improve the functioning of you home

Monochuche render, so, why choose monocouche?

The main reason? Damp proofing! Monocouche can cure penetrating damp.

On a formulation level, the type of cement used in monocouche renders allows for pigmentation to be added which is what gives it a through-coloured appearance and means there’s no need to paint it.

Monocouche has many benefits for the homeowner

  • Through-coloured render which is low maintenance, strong and long-lasting
  • Can be applied by hand or pumped with a machine, saving time and effort
  • One coat application
  • Monocouche is a one coat render applied in two passes, finished to a thickness of 15-25mm
  • Can be scrape finished for a modern appearance or sprayed roughcast for a traditional look

It’s easy to see why monocouche render has been so popular over the years – it’s a fantastic product. Unlike a traditional sand and cement render, monocouche is single-coat and through-coloured which means it doesn’t need to be painted.

External Coatings

Here at Dryseal we use a unique micro silicone emulsion to stop water penetration. We apply just one coat of dry seal coating directly onto damp surfaces to provide long lasting waterproof protection within hours. It can be used on brickwork as well as render and can also be applied whilst the service is still damp. The solution is clear so will not mark or stain.

Woodworm Treatments

Woodworm is a simpler term for wood-eating larvae. In addition to identifying the type of woodworm, our woodworm treatment will also depends on the extent of the problem, what stage of growth it is in, and various other factors such as moisture content, dry/wet rot and any additional damp problems in the property. This is why our specialists at Dryseal will investigate each case of potential woodworm infestation closely, provide a diagnosis, and select the correct treatment for the job.

The Process

  • Firstly, our surveyors will survey your property.
  • Once woodworm is indeed confirmed, our specialists will:
  • Identify the scale and severity of the woodworm infestation
  • Determine an appropriate treatment

  • Identify any further repairs required to fix the problem (for example; correcting a damp issue)
  • Provide a quotation for the work before proceeding
  • On acceptence of the quote, proceed accordingly

Solving Condensation and Mould

Are you experiencing Condensation, Damp and Mould issues in your home?

Are you sick of being told the only solution is open the windows?

Or being asked to buy certain expensive branded mould remover or "special" dampproofing paint? For the problem to just come back within weeks of application, only masking over the underlying issues.

Here at Dryseal Damp Proofing Services Ltd we have the answer to the problem using Positive Input Ventilation (Piv) Units.

How does it work?

Our heated PIV Systems draw fresh air from the outside into a mounted unit in your loft. The fresh air is then filtered and blown through a ceiling diffuser in your hallway. The unit then gently pressurises your home helping dilute and displace the stale moisture air with fresh filtered air. Getting rid of your Condensation, Damp and Mould issues for good.

Other Benefits of PIV?

  • Very low running costs
  • Energy-efficient
  • Quick Installation with minimal disruption
  • Helps Asthma Suffers
  • Low maintenance
