About Us

My Name is Paul Redston, I first began in this industry in 1996 as A1 building services. I don’t have a fleet of vans or staff, I simply carry out all of the above work myself, so you can be assured that when I give you a price for the works that are needed, it will be me doing the job and me you will be paying at the end. I always do what is right for the building by using the correct products regardless of the cost.

I only specialize in the work listed,

  • DAMP PROOFING
  • CAVITY WALL TIES
  • DRY & WET ROT
  • CONDENSATION CONTROL
  • TANKING SYSTEMS

RISING DAMP

Rising dampness is caused by moisture rising in the walls by capillary action. If severe, there will be a tell-tale stain line around the wall and wallpaper may be peeling away. Rising dampness may also cause the skirting boards to rot.

Persistent rising dampness will take chlorides, nitrates and other salts from the soil, which are deposited on the face of the plaster as the water evaporates from the surface. Such salts are hygroscopic, with the effect that the face of the plaster has a tendency to be persistently damp, particularly during periods of high humidity of the atmosphere even after the rising dampness has been arrested.

Many older properties can be affected by rising damp due to the lack of an effective damp proof course, this often being slate or bitumen. Existing damp proof courses can also become ‘bridged’ by high external ground levels or can over time break down.

I use a product called pam cream to effectively treat rising dampness in buildings. This is a ‘cream’ which is injected into the walls via 12mm holes which are drilled into the mortar. Once the pam cream is installed, it diffuses before curing to form a water-repellent resin which prevents further dampness rising up the wall.

In conjunction with any chemical damp proof course injection works that may be undertaken, it is always recommended that affected walls be stripped of contaminated plaster up to a minimum height of 300mm past the last damp readings. Our own specialist plasterers will then reinstate the plaster to specification incorporating a salt retardant additive.

In some instances, it may be found that dampness issues within a property are due to defects such as faulty rainwater goods, porous pointing or ‘bridging’ of the existing damp proof course. Often the presence of internal mould, normally associated with condensation, can sometimes be mistaken by householders as rising or penetrating damp.

TIMBER TREATMENTS

Wet Rots and Dry Rot can be easily misidentified by the layman. However, it is always sensible to get any fungal growth checked by an expert. People assume that Wet Rot affects wet timber and Dry Rot affects dry timber but, in fact Dry Rot requires a high moisture content within the timber.

It often affects timbers located next to damp walls and likes humid, unventilated spaces in buildings. Once established it is very persistent and, will travel long distances, often behind wall plaster to find further damp wood to devour.

Affected timber shows signs of cuboidal cracking and when severely affected, crumbles readily into fine powder. Fungal mycelium develops on the surface of the timber, sometimes this mycelium looks like a white, cotton wool cushion, which spreads across timbers and brickwork. Strands radiate from the initial outbreak and can extend for several feet across inert materials such as bricks and steel joists etc.

The fruiting body resembles a flat plate or bracket. They are initially pale grey but as spores develop on the spore-bearing surface, it becomes rusty red in colour. Millions of spores are produced and this gives rise to the characteristic red dust which can cover a floor.

Treatment must be a comprehensive sterilisation to one metre beyond the last visible sign of growth and it is essential to determine the full extent of the outbreak and ensure that no infected timber is overlooked. All fungus growth will need to be traced to its origin and all hidden timbers uncovered. It is also essential to locate and rectify the source of moisture ingress giving rise to the fungal decay.

This type of Rot can cause extensive damage to a property and it is always advisable that a survey is carried out as quickly as possible once an outbreak is suspected.

CONDENSATION CONTROL

Condensation is created by moisture which accumulates from everyday living. Many properties, especially flats and bungalows, suffer from condensation.

What Causes Condensation?

A common route of condensation is caused by the ever improving standards or insulations, double glazing and draught proofing in properties. These installations boast obvious benefits in their retention of heat; however it can result in poor air ventilation, stale air, and trapped moisture. Over time this lack of ventilation can result in unhealthy living conditions.

Condensation on Windows, Walls, Loft etc

The signs of condensation include; water collecting on your windows, water on your window sills, tiles and walls, black mould growth, peeling decorations and musty damp smells.

Condensation Solutions/Cures

I have a full range of anti-condensation units that can be fitted into the loft space or fixed onto the external walls. This improves air quality by removing the excessive moisture laden air. Passive core vents can also be fitted for increased ventilation. Another solution combines the fitting of an anti-condensation unit with thermal plaster-boarding, which saves on heating bills. This can be fitted internally or externally and is a great benefit for older properties.

CAVITY WALL TIES

wall tie is a steel bar, strap or twisted wire which is built into a double skin or cavity wall to hold the masonry together; usually made of mild steel. Wall ties are crucial to the stability of external walls.

Older ties were made of a thick mild steel bar formed into the shape of a fishtail. More modern ties are made of a twisted wire and form the shape of a butterfly.

Any building with cavity walls built prior to 1981, an estimated 10 million dwellings, could be prone to wall tie corrosion and failure.

If the steel of a wall tie is exposed to air and oxygen, the all too familiar rusting cycle begins. The loss, by rusting and corrosion, of the wall tie is one problem but the other major consideration is the increased volume of the steel, causing mortar to split and lift. This will result in instability of the cavity wall and the likelihood of it moving out of plumb.
