Facade sealing in Merton Park
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. We work on perimeter joints where frames meet the structure, window and door perimeters and stone and brick facade joints, and the failures we are asked to look at most are weathered joints at frame-to-structure perimeters and facade joints cracked through the middle. A single leaking joint is often how a building in Merton Park first comes to us: we look at the rest while we’re there and tell you what we find.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Merton 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 ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Commercial clients in Merton Park
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Mastic packages on Merton Park sites
A 2-mile radius around Merton Park takes in plenty of hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Merton Park. Deliveries are booked and storage is tight, so mastic materials come in as needed.
Building work at universities like Kingston University Roehampton Vale Campus (to the north-west of Merton Park) is often timed for the summer, mastic included. Hotels like Antoinette Hotel (0.7 miles north-east of Merton Park) rarely close for long, so refurbishment mastic is phased floor by floor.
Merton Park is about 1 mile south-east of Wimbledon, in Greater London. Anywhere in SW19, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places. Our London page has more on work in that area, about 8 miles away.

Local landmarks in Merton Park

Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In Merton Park, 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.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Share the asbestos register for older buildings
- Point out any areas we must not close

What we’re called out for in Merton Park
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
If one of these sounds familiar, it’s time for a closer look:
- Failed sealant on precast panel joints
- Failed seals around shopfront and entrance frames
- Unsightly perimeter sealant on a visible elevation
- Cold air coming in at window perimeters
When a college such as Wimbledon College of Arts (0.5 miles north-west of Merton Park) builds or refurbishes, the mastic package normally has to fit around students and staff.

Surface by surface
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.
Leave it or put it right?
Open facade joints also let air and dirt through: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Getting scaffold, permits or access booked in Merton Park takes effort, so it makes sense to deal with every failing joint while access is in place.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What you get with us
- Matching to RAL references, product permitting
- 12-month guarantee on workmanship
- Products installed to the manufacturer’s instructions
- Over 20 years of commercial sealing

Cost factors for facade joints
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Backing rod, priming and other preparation
- How much existing material needs removing
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Sending details for a quote
Good information means a firmer quote. When you get in touch, include:
- Asbestos survey details if the building is older
- Specification clauses that apply
- Photos of the joints, close up and from further back
- Access details, including height
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.
Your questions answered
Do you take on jobs in Merton Park where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
Do you take on work at healthcare sites like St George's Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
How much does the work cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work on upper floors?
We agree access with the client at the start. Tell us about access: existing scaffold, what you are arranging and any site restrictions.
Will you check whether the sealant is causing the leak?
Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will be honest about which it is.
