How we handle construction mastic in Mortlake
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, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. If you have old sealant on a refurbishment that needs stripping before new work and frame perimeters left unsealed or poorly sealed, we can help, whatever the surface. One point of contact handles commercial sealant work in Mortlake from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Construction in a London area such as Mortlake means working on constrained sites: 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.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we’re called out for in Mortlake
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens.
These are often picked up first by site or facilities staff:
- Internal caulk splitting as the building dries out
- A long mastic snag list close to completion
- Missed perimeter joints on a new elevation
- Old sealant on a refurbishment that needs stripping before new work
Work at a hotel such as Kew Gardens Hotel (to the north-west of Mortlake) tends to be programmed around bookings, mastic included.

Leave it or put it right?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. Sound frames often need only a new perimeter seal, which is a much smaller cost. If the frame is life-expired, we will tell you. In Mortlake, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- Coloured sealants to suit the setting, where available
- Public liability insurance in place
- Joints cleaned back to sound surfaces
- 12-month guarantee on workmanship

Common questions from Mortlake clients
Is Kew Retail Park, near Mortlake, within your area?
Yes. Our area takes in Mortlake and its surroundings, with estates and business parks such as Kew Retail Park included. A few photos and the unit address let us price the work.
Can you work on a hospital site such as Barnes Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can staff carry on working while you are here?
Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.
What will the job cost?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or send photos by email.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Other services in Mortlake
Surface by surface
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
Internal decorators’ caulk
Caulk is easy to apply badly. A neat, consistent caulk line makes the decorators’ job quicker and keeps the snag list down.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Don’t schedule sealing before decorators and flooring are done
- Ask for joint and product checks before the package is urgent
- Don’t force external sealing on a damp or frosty day
- Stick to the specified sealant rather than a generic substitute
Record which products went where in the handover file. Future maintenance is easier when the products are known, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last so packing or adjustment by the installer comes first. We flag them as soon as we see them.
Work for main contractors and building owners
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
Building and refurbishing in Mortlake
There are plenty of hotels within about 2 miles of Mortlake. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. The ULEZ covers the whole of Greater London, Mortlake included, so site vehicles need to meet its standards or pay the daily charge. Delivery slots and scarce storage shape how and when the mastic goes in.
Hospital estates such as Barnes Hospital (under half a mile east of Mortlake) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Building work at universities like University of Roehampton (to the south-east of Mortlake) is often timed for the summer, mastic included.
Mortlake is about 3 miles west of Fulham, in Greater London. Across the SW14 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Mortlake is one of 764 places in Greater London on our list for mastic packages. There’s a separate page for London, roughly 8 miles from Mortlake.
We cover the SW14, SW13 and SW15 postcode districts. If your site is on Elm Road, Well Lane and Coval Road or close by, send details and we’ll quote for mastic packages. You’ll find Mortlake on or near the A3003, so getting applicators and materials to site is simple. If your building is just outside Mortlake, we cover East Sheen (1 mile south-west), North Sheen (1 mile north-west), Barnes (1 mile north-east), Grove Park (1 mile north) and Roehampton (1 mile south-east). Nearby towns on our patch include London (8 miles east), City of Westminster (6 miles north-east), Marylebone (6 miles north-east), Kensington (4 miles north-east), St Pancras (8 miles north-east) and Shoreditch (9 miles north-east).
Local landmarks in Mortlake

A little further out are Ubuntu Museum: African Museum of Humanity (1.1 miles south-east) and Barnes Hospital (under half a mile east). Green spaces nearby include Richmond Hill and Kew Gardens Lake.
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Mortlake can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- Drawings, specification and programme come to us.
- Quantities are measured and a fixed price returned.
- We agree with the site team which areas come first.
- Plots or floors are sealed as they’re handed over.
- Joints are prepared, backed and sealed to the specification.
- Snags are cleared and the package signed off with our 12-month guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Move anything stored against the joints
- Send any specification or drawings in advance
Quotes
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
