External mastic in Stratford St Mary
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. We work on copings & trims, brickwork movement joints and façade panels, and people most often call us about gaps where render, brick and frames meet and brick movement joints where the sealant has split.
Outside joints can only be sealed when they’re dry, so work in Stratford St Mary is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
All our work comes with our 12-month guarantee, wherever you are in Essex.

Should I try it myself first?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How long will you be here?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We’ll tell you when we quote.
Why do you put foam in the joint first?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Landlord and commercial work in Stratford St Mary
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Looking after it afterwards
Aftercare is simple:
- Keep high-pressure jets off the joints
- Point out the joints to other trades
- Fix overflowing gutters above sealed joints
- Check external joints each spring
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.
Outside joints around Stratford St Mary
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Castle House (about 1.7 miles south-east) nearby, there’s older building stock in the area around Stratford St Mary as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you let a flat or house near Manningtree station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Stratford St Mary Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

When it is not the sealant

- Rising or penetrating damp from elsewhere in the wall
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal

- Copings & trims
- Concrete & block
- Render & cladding joints
- Joints between brick and frames
- Brickwork movement joints
When to call us in Stratford St Mary
Sometimes a movement joint was filled with mortar or a rigid filler. The joint cannot move, so the wall cracks somewhere else instead.
People generally contact us after spotting one of these:
- Moss and dirt in joints with no sealant left
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
In the older streets around Church of St Mary, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Questions to ask before booking
- When the joint can take water or movement
- The length of the guarantee
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
What we do, step by step
The work is kept neat and contained to the joints we are treating. The job usually takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. For a village or hamlet like Stratford St Mary, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
