External mastic in New Street, 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. If you have joints with sealant missing in places and joints where the bead has come unstuck, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around New Street is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Can I do it myself?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
- Cutting new joints into brickwork, which is building work rather than sealant work
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.

What external mastic looks like in New Street
With historic houses such as Cobham College (about 3.6 miles north-east) nearby, there’s older building stock in the area around New Street 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of Saint Peter include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Meopham station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Culverstone Green Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What the job involves on each surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that’s happened, we rake it out and reseal it properly if the joint can be cleared.

Advice
FAQs for New Street
Will you come out to New Street?
Yes, New Street is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Meopham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
How do you reach high-level joints?
It depends on the building. Send us pictures and a rough idea of the height and we’ll confirm how they can be reached safely.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
How do I get a quote for external mastic in New Street?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- When we can work, for business premises
- Whether the work is at height
- The size of the job
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Leave the joints unpainted unless we’ve said otherwise
- Make sure movement joints aren’t pointed over
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
