Facade sealing near Barnes
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- Phasing around occupants
- Any access equipment needed
Access often affects the price as much as the sealing: 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.
What we need to price the job
However big the job, these details speed things up:
- How the joints are reached, and at what height
- Whether the building will be occupied during the work
- The postcode of the building
- Any dates the work must fit around
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
Facade sealing in Barnes, done properly
Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around. If you’re dealing with air leaks through failed facade joints and perimeter joints where frames meet the structure, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Barnes, that means joint design, primers and backing rod as standard.
Construction in a London area such as Barnes means working on constrained sites: limited storage, booked deliveries and access shared with other trades. We fit around the programme, sealing each elevation or floor as other trades hand over.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

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.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Damaged frames that need replacing
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Specialist high-level access methods
If in doubt, call 01277 525 020 or send details through our quote form and we will say what we think.
Joints and surfaces we work on
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Stone and brick facade joints
- Coping and flashing joints
- Window and door perimeters
- Shopfront frames
What happens if it’s left?
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Failed sealant in a building in Barnes can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Keeping the joints sound
A few simple habits keep the new joints working:
- Share access with other external trades
- Keep the sealant details on the building file
- Keep sills, gutters and drainage paths clear
- Insist on a full cut-out when joints are renewed
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.
Your questions answered
Could you schedule work at a campus like University of Roehampton for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is a hospital such as Barnes Hospital somewhere you can work?
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.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How do I request a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Mastic packages on Barnes sites
A 2-mile radius around Barnes takes in a good number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. The ULEZ covers the whole of Greater London, Barnes 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 University of Roehampton, which lies south of Barnes, facade and perimeter sealing has to fit around students and term dates. Recladding or extending a unit at a site like Kew Retail Park, 1.5 miles west of Barnes, brings panel joints and frame perimeters into the programme. Hotels like Putney Hotel, 1.4 miles south-east of Barnes, rarely close for long, so refurbishment mastic is phased floor by floor.
