Construction mastic for commercial buildings in Middle Park
Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. Most enquiries involve existing joints on a refurb that need cutting out and resealing and bath and shower joints scraped during the final clean, across cladding and panel joints, internal decorators’ caulk and brick and block movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Middle Park it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Middle Park must meet its standards or pay the daily charge. Add booked delivery slots and limited storage, and a London mastic package needs planning before the first bead.
Every job we finish is backed by a 12-month workmanship guarantee, in Middle Park as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification rather than at the snagging stage. Leave it late and they turn up on the snag list. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What you get with us
- Colour agreed before work starts
- Products installed to the manufacturer’s instructions
- Old sealant cut out, never sealed over
- Fully insured
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Location, for remote and island sites
- The site’s rules and procedures
- Phasing around occupants
- The size and state of each joint
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Send us:
- Drawings or a marked-up plan, if available
- Whether an asbestos survey exists
- Anything awkward about access or site hours
- Clear photos of the problem areas
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

When to call us in Middle Park
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
Typical triggers for a call:
- Existing joints on a refurb that need cutting out and resealing
- Early adhesion failures on new external joints
- Window and door perimeters that won’t pass inspection
- Sanitary sealant damaged by following trades
Building work at universities like University of Greenwich - Avery Hill (to the east of Middle Park) is often timed for the summer, mastic included.

- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
- Who will actually carry out the work
FAQs: Middle Park
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Can you work around term dates at a campus such as University of Greenwich - Avery Hill?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you cover Middle Park?
Yes. Middle Park falls within our area, and you can call the office on 01277 525 020 or use the quote form to get started.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, normally a low-modulus neutral-cure silicone and set the depth with backing where needed.
