Leave it or put it right?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Halls, stores and units around places like Three Chimneys may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Why us?
- One contact handling all your sites
- A Constructionline member, so easy to vet
- A range of standard colours, depending on the product
- A fixed quote before work starts

Mastic sealing in Three Chimneys
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. If you’re dealing with draught complaints from residents or tenants and cracked, hardened mastic round windows on a block, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Three Chimneys it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places like Three Chimneys, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Questions about Three Chimneys
Can you quote for mastic across several buildings in and around Three Chimneys?
Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we’ll give a fixed quote.
Is Three Chimneys too small for you to travel to?
Not at all. Three Chimneys is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you take on resealing for a block portfolio?
Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.
What if the old mastic contains asbestos?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
What guarantee do you give on resealing?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day.
Commercial clients in Three Chimneys
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Three Chimneys. One quote can cover more than one site, so there’s one set of paperwork to deal with.
What we can’t put right
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Masonry that has broken away beside the joint
- Glazing that needs replacing
- Frames that are rotten, warped or broken
If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use.

Keeping the joints sound
A few simple habits keep the new joints working:
- Share the asbestos register when you send details
- Encourage occupiers to report problems at frames
- Group repairs into a planned programme
- Share your contractor requirements early
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.
