Construction mastic in Coombe Hill
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. We work on floor and skirting junctions, cladding and panel joints and sanitary and kitchen joints, and what we are called in for most is sanitary sealant damaged by following trades and cracks opening in caulked internal joints. Most enquiries from Coombe Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job we finish is backed by a 12-month workmanship guarantee, in Coombe Hill as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Different surfaces, different methods
Fire-rated sealant where specified
Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we’ll confirm with the quote.
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.
Common problems we fix in Coombe Hill
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.
Look out for the following:
- Missed perimeter joints on a new elevation
- New external sealant already peeling away
- Failed sealant in an existing building being refurbished
- Cracks opening in caulked internal joints
When a college such as Kingston College Creative Industries Centre (2 miles south-west of Coombe Hill) builds or refurbishes, the mastic package normally has to fit around students and staff.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
- Will RAMS and insurance details be available?
Your questions answered
Is a hospital such as New Victoria Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you plan work around the academic year at somewhere like Kingston University (Kingston Hill Campus)?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How much does the work cost?
Every job gets its own fixed quote. For yours, phone 01277 525 020 or use the quote form.
What guarantee comes with a mastic package?
The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can fire-rated sealing at service penetrations be included?
Where it’s specified, yes, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we’ll tell you.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

New build and refits around Coombe Hill
Coombe Hill has plenty of hotels close by, all within 2 miles. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. The ULEZ covers the whole of Greater London, Coombe Hill included, so site vehicles need to meet its standards or pay the daily charge. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors on a campus like Kingston University (Kingston Hill Campus), which lies south of Coombe Hill, facade and perimeter sealing has to fit around students and term dates. Units on estates such as St. George's Industrial Estate (to the west of Coombe Hill) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Building owners, agents and FMs in Coombe Hill
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Honest limits
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Frames fitted out of tolerance
- Joints damaged after sign-off by following trades
- Joint design decisions that belong to the architect or engineer
If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think before you book.
Joints and surfaces we work on
- Cladding and panel joints
- Brick and block movement joints
- Sanitary and kitchen joints
- Window and door perimeters
- Floor and skirting junctions
- Internal decorators’ caulk
Quoting for work in Coombe Hill
Quotes vary with the job. Expect it to depend on:
- Site requirements such as inductions and permits
- How accessible the joints are
- Location, for remote and island sites
- Whether the work must be split into stages
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Specification clauses that apply
- Access details, including height
- Where the site is, with the postcode
- Photos of the joints, close up and from further back
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Our process
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. In Coombe Hill, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First we take quantities off the drawings and read through the specification.
- We return a fixed quote that ties the mastic package to your programme.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Have the specification and drawings to hand
- Flag any permit to work we’ll need
