External mastic for homes and businesses in East Street
Low-level joints can generally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you are dealing with old sealant gone brittle and cracked and cracked joints where brick meets render or frames, we can help.
Around East Street, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water usually gets in, and they need the right sealant at the right depth.
All of our work is guaranteed for twelve months.

Walls and rooflines in East Street
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 Goodnestone Park (about 4.3 miles south-west) nearby, there’s older building stock in the area around East Street as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Letting a property close to Sandwich station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Sandwich Technology School, larger buildings have long runs of movement joint that eventually need resealing.

East Street questions
I let a flat near Sandwich station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like East Street?
Yes. East Street is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we will sort it.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. It’s closed with backing rod and a flexible sealant.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.
Landlord and commercial work in East Street
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.
Why it’s worth doing now in East Street
Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. Where a wall is exposed, as many are in small places like East Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: 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’ll explain what it covers.

- White, clear, grey or coloured to suit, where the product allows
Signs you need external mastic in East Street
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
If you can see any of these, it’s time to have the joints looked at:
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
- Joints with sealant missing in places
- Moss and dirt in joints with no sealant left
In the older streets around Church of St Nicholas, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- How long to leave it before use
- Whether VAT is included
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first
How it works
On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like East Street, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

What we can’t put right

- Cracks in the bricks or render themselves, away from the joints

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

- Joints between brick and frames
- Render & cladding joints
- Façade panels
Can I do it myself?
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 fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, 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.
What affects the quote in East Street
There’s no set price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Whether there’s mould to deal with
- Which sealant suits the joint
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Asking for a quote
