How we handle external mastic in Burlow
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. We work on brickwork movement joints, concrete & block and copings & trims, and common reasons people get in touch are sealant that has lost its bond to the brick or render and plants rooting in failed movement joints.
Outside joints can only be sealed when they’re dry, so work in Burlow is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
Big or small, you get the same 12-month guarantee in Burlow and across East Sussex.

Why act early in Burlow
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Where a wall is exposed, as many are in small places like Burlow, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.

Walls and rooflines in Burlow
Historic houses like Horselunges Manor (about 2.8 miles south) are a reminder that the area around Burlow 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around Burlow, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Signs you need external mastic in Burlow
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Keep an eye out for any of the following:
- Weeds or debris growing in open joints
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Weathered mastic that no longer stretches
In the older streets around Christ Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Questions from Burlow
Can you do external mastic in Burlow?
Yes, Burlow is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Will you come out to Burlow?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you guarantee your work?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How long will you be here?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. We will confirm how long when we quote.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
