About our external mastic in Fairford Leys
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. Common call-outs are for failed sealant between panels on a façade and rain getting behind render or cladding at a joint, on brickwork movement joints, copings & trims and render & cladding joints.
Around Fairford Leys, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
You get a 12-month guarantee, the same in Fairford Leys as everywhere else we work.

How the visit works
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a smaller place like Fairford Leys, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Clear the area around the work

FAQs for Fairford Leys
Is Fairford Leys within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Aylesbury station?
Yes, we work for letting agents and landlords. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What we are called out for in Fairford Leys
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Common reasons people contact us are:
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
- Sealant that has lost its bond to the brick or render
Schools such as St Mary's Church of England School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.
What to look for in a quote
- Whether you can choose the colour
- When the joint can take water or movement
- How hidden problems are handled
- Whether VAT is included
Walls and rooflines in Fairford Leys
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Waddesdon Manor (about 4.6 miles north-west) are a reminder that the area around Fairford Leys has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
In the older streets around Fairford Leys Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. Rented homes near Aylesbury station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Should I try it myself first?

Why it’s worth doing now in Fairford Leys
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In a smaller place like Fairford Leys, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
