External mastic for homes and businesses in Loughton
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what access is needed. If you have hard, crazed mastic that has stopped moving and weeds or debris growing in open joints, we can help, whatever the surface.
Around Loughton, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Where two materials meet, they move differently, and the sealant has to allow for it.
There’s a 12-month guarantee on every job.

Why act early in Loughton
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a family home in Loughton, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before work begins.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Leave the joints unpainted unless we have said otherwise
- Never let anyone fill a movement joint with mortar
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
External mastic in Loughton: local notes
With historic houses such as Hill Hall (about 4.1 miles north-east) nearby, there’s older building stock in the area around Loughton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
In the older streets around St. John's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like The Alderton Infant School? Then its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Chingford station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Questions from Loughton
Can you do external mastic in Loughton?

Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including the preparation. Your quote will say how long we expect yours to take.
Why is there a gap in my brick wall?
Brickwork, render and cladding all move a little, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Different surfaces, different methods
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
Brick against render, concrete against metal, stone against timber: every change of material is a joint. A flexible sealant bridges the two so neither cracks the other.
How it works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building in most cases. In Loughton, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Tell us if parking is tricky
- Clear the area around the work
- Mention if the joints have been sealed before
