Mastic sealing for businesses in Stone Corner
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Looking after the joints
Once the work is signed off, these steps help:
- Have the asbestos survey to hand for older buildings
- Encourage occupiers to report problems at frames
- Share your contractor requirements early
- Check sealant joints during planned building inspections
Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.
Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
Mastic sealing in Stone Corner
Across Stone Corner and the rest of Kent, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote or we can visit. The enquiries we see most involve repeated reactive repairs to the same buildings and damp patches beside frames, on communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints. Facilities teams, main contractors and managing agents in Stone Corner tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Stone Corner, we group work so one trip covers it. Photos of each elevation help us quote accurately.
A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we’ll come back to it.

Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Planned mastic for Stone Corner portfolios
Central London is about 48 miles from Stone Corner. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Rainfall across the South East, Stone Corner included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Appledore (Kent) station (3.9 miles east of Stone Corner), frame and balcony mastic can be renewed on one programme. Older buildings near Stone Corner, from historic houses such as Smallhythe Place, 1.4 miles north-west of Stone Corner, to more modest stock, need compatible products when frames are resealed. Landlords with units on estates such as Pickhill Business Centre, 2.3 miles to the north-west of Stone Corner, can bring frame, door and external mastic across several units into one programme.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Roof leaks, gutters or failed flashings that aren’t sealant joints
- Leaks through the frame itself rather than the perimeter
- Misted or failed double-glazed units
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.
What we seal
- Communal kitchens and washrooms
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
- Communal entrances and stairwells
- Window and door perimeters on blocks
Your questions answered
Is a smaller place like Stone Corner outside your area?
Not at all. Stone Corner is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you cover business parks and estates near Stone Corner, such as Pickhill Business Centre?
Yes. Estates, retail parks and business parks around Stone Corner, Pickhill Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Can you seal joints high up on a block?
It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.
Can you take on resealing for a block portfolio?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
What sets the cost
Each job is priced on its own details. The main factors are:
- How accessible the joints are
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- Whether the work must be split into stages
A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- Asbestos survey details if the building is older
