Nash questions
Is Nash within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Nash for external mastic?
Yes. We work across London and the South East, and Nash is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.
How long will you be here?
That depends on how much there is to do, but most jobs take anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin, matched as closely as the range allows.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we will confirm the access.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What does external mastic cost?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email and tell us what needs doing and where.
External mastic for homes and businesses in Nash
On houses, flats and commercial buildings across Nash, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. If you’re dealing with old sealant gone brittle and cracked and movement joints filled with mortar instead of sealant, we can put it right, whatever the surface.
Around Nash, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or email us.

External mastic in Nash: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of All Saints include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Milton Keynes Central station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Keeping the joints in good condition
So the new joints stay in good condition:
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Tell anyone working on the walls about the movement joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What the job involves on each surface
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
What happens on the day
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours to a few days, depending on the length of joint and the access in most cases. Somewhere as small as Nash, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
