External mastic for homes and businesses in Roxwell
For buildings in Roxwell, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on render & cladding joints, façade panels and copings & trims, and people most often call us about rain getting behind render or cladding at a joint and movement joints with cracked, split or missing sealant.
External sealant needs dry, clean surfaces, so work around Roxwell is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

What we do, step by step
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes anything from a few hours to several days, depending on the building, depending on the amount of work. In a small place like Roxwell, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- 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 any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

What else we do in Roxwell
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Fix overflowing gutters above sealed joints
- Make sure movement joints aren’t pointed over
- Look over the joints every year, ideally after winter
- Tell anyone working on the walls about the movement joints
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead.
Act while the splits are small. At that stage it’s a simple cut out and reseal.
What external mastic looks like in Roxwell
Historic houses like Hylands (about 3.5 miles south-east) are a reminder that the area around Roxwell has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. 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.
If you live in an older home near Church of St Michael and All Angels, the joints between older walls, newer extensions and the roofline need a sealant that can move. If you let a flat or house near Chelmsford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Roxwell is about 4 miles west of Chelmsford, in Essex. Whether you are in the middle of Roxwell or further out, we cover external mastic for every kind of property, from flats and houses to offices and hotels. Across Essex, we cover 644 places, and Roxwell is one of them.
Work in CM1 works the same way as everywhere else we cover. If you need external mastic at a property on The Street, Church Green and St Michael's Drive or a nearby road, we can help. If you are just outside Roxwell, we cover Boyton Cross (1 mile north-east), Newney Green (1 mile south), Chalk End (2 miles north-west), Shellow Bowells (2 miles west) and Radley Green (2 miles south-west). We also work in nearby towns such as Chelmsford (4 miles east), Basildon (13 miles south), Braintree (12 miles north-east), Harlow (12 miles west), Brentwood (9 miles south) and Maldon (13 miles east).
Around Roxwell
We work in homes and buildings around The Chequers Inn and the streets around them. Roxwell’s nearest station is Chelmsford station, about 3.8 miles east. A little further out are Willingale Doe (2.8 miles west) and Peter Edwards Museum And Library (3.9 miles east). Open spaces near Roxwell include Newland Grove.
Leave it or put it right?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. Where a wall is exposed, as many are in small places like Roxwell, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

DIY versus a professional finish
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 does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What the job involves on each surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.
