Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Mastic sealing in Founthill
Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. If you have failed external movement joints and draughts at frames across a block, we can help. Facilities teams, main contractors and managing agents in Founthill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For buildings around smaller places like Founthill, we group work so one trip covers it. Send photographs of the frames and joints and we’ll give a fixed quote.
A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email us and we will come back to it.

Common problems we fix in Founthill
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
Common reasons buildings call us in:
- Communal area joints that look neglected
- Complaints coming in block by block
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
For owners of several units at places like Bellbrook Industrial Estate, 2.8 miles east of Founthill, one programme can deal with frame and external mastic across the lot.
Before you book anyone
- How they’ll work around occupants
- What level of public liability insurance do they hold?
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:
- Failed window or door frames, which need a window contractor
- Leaks from above rather than through a joint
- Glazing that needs replacing
If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer.
What we seal
- Shopfronts below residential blocks

Founthill: questions and answers
Is a smaller place like Founthill outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you take on a block within reach of Uckfield station?
Yes, and several blocks can go on one quote. Photos of each elevation help us quote accurately.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you follow the specification on our project?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Can people stay in the building while you reseal?
We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told and communal access is kept open.
How the job changes by surface
Communal areas
Low-level communal joints get damaged more than most and tend to fail first.
External movement joints
Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Share the asbestos register when you send details
- Log resealing dates block by block
- Make mastic part of routine maintenance checks
- Prioritise elevations facing the weather
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
From enquiry to sign-off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Founthill can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready

- Flag any permit to work we’ll need
Request a quote
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to phone 01277 525 020 or send photos by email.

Mastic sealing in Founthill: the local picture
At about 37 miles from central London, Founthill is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide. Rainfall across the South East, Founthill included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.
If you’re responsible for a building such as The Parish Church of St Mary, frame and door mastic needs the same attention as any other property. For agents with blocks near Uckfield station, which lies east of Founthill, a block-wide mastic programme deals with frames, balconies and entrances in one go.
Founthill is about 3 miles west of Uckfield, in East Sussex. Any commercial site in Founthill is covered. We work across 308 places in East Sussex. Our Brighton page has more on work in that area.
