External mastic for Lidsing and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Sealant pulling away from one side of the joint
- Rigid filler in a joint that should flex
- Cracked joints where brick meets render or frames
External mastic in Lidsing, done properly
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement. We work on brickwork movement joints, façade panels and concrete & block, and common reasons people get in touch are weathered mastic that no longer stretches and weeds or debris growing in open joints.
In a village or hamlet like Lidsing, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Landlord and commercial work in Lidsing
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Why deal with it now?
Water gets in through a failed movement joint, behind render and cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a small place like Lidsing, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

What the job involves on each surface
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.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
How it works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Lidsing, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in

When it is not the sealant
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

Lidsing buildings and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Restoration House (about 4.7 miles north-west) nearby, there’s older building stock in the area around Lidsing 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 Rainham (Kent) station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. For site and facilities teams at buildings such as Swingate Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Church of St Peter, an extension built onto an older house moves differently, and the joint between them takes the strain.

- The old material and how stubborn it is
- The number of rooms or windows
- Any working-time requirements on site
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
FAQs for Lidsing
Will you come out to Lidsing?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Lidsing for external mastic?
Yes. We work across London and the South East, and Lidsing is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long does the job take?
As a guide, most jobs take anything from a few hours to several days, depending on the building. Larger jobs naturally take longer, and we’ll say how long yours will take.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we are using.
Do you work at height?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we’ll confirm what’s needed.
