Roofing in York
The sky's the limit if you have a roof over your head! – Sol Hurok
If water's coming through the roof, contact us as soon as possible!
Climbing onto the roof should be left to the professionals, but if you absolutely must, remember that the rafters may not bear your weight. A special roof ladder with wheels to speed it along the tiles without damage and a large hook to hold it in place can be hired from HSS Hire.
Whether you've noticed signs of damp or just want to pre-empt potential problems, make some basic checks. Stand on the opposite side of the road or in the garden and use binoculars for a closer inspection.

Damp proofing is often the most appropriate treatment for properties which have identified damp problems, such as rising damp or penetrating damp.
There are a number of ways that damp proofing can be carried out, which will include either of the following options or even a combination, if that is what is required to solve the damp problem.
Installation of a chemical injected damp proof course together with associated re-plastering
A structural waterproofing system incorporating a damp proof membrane and possible sump pump.
The use of conventional cementitious tanking system.
We offer guarantees with our damp proofing treatments for both rising damp and penetrating damp.
The use of a low odour water-based silicone injection is generally regarded as the most effective type of damp proof course to prevent moisture rising through a wall and leading to rising damp.
Dependant on the thickness of walls, holes are drilled in the mortar / brick of external and internal walls to a pre-determined depth and at the correct level and spacing between holes.
These holes are then injected with damp proofing fluid (water-based silicone) to reduce the movement of water through the capillaries.
Damp proofing fluid should not be confused with a damp proof membrane.
The term membrane usually suggests a physical barrier, whereas the principal of silicone injection is to line the pores of the wall structure to stop moisture vertically rising by capillary action. The silicone does not block the pores of the wall, it only lines them.
Following the insertion of a damp proof course it is common for re-plastering to be required. Any new plastering has to prevent damp and salts present within the wall migrating onto the internal wall finish.
The most common approach to re-plastering is using a dense sand and cement render as a backing coat incorporating a waterproof additive. Once dry, a gypsum skim coat is applied to give a smooth finish.
When the existing plaster is removed, there may be a lot of dust. We advise that adequate steps are taken to remove or cover furnishing for protection.
Following re-plastering a minimum of at least two weeks must elapse before the new plaster can be decorated and all areas need to be visibly dry.
At this time decoration should only be with a water based permeable emulsion, vinyl paints should not be used.
Permanent decorations such as wall papers can be applied when the wall is fully dry, which can take up to a year and in some cases much longer.
