How we handle facade sealing in Richmond upon Thames
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure for clients around Richmond upon Thames. Coping and flashing joints are included where sealant is the specified fix. The enquiries we see most involve air leaks through failed facade joints and staining on stone next to old sealant, across perimeter joints where frames meet the structure, stone and brick facade joints and coping and flashing joints. For commercial sealant work in Richmond upon Thames, you deal with one contact from quote to sign-off, whether it’s one building or several.
Construction in a London area such as Richmond upon Thames means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Arranging specialist high-level access, which is planned with the client
- Cracked or spalling substrates that need repair before sealing
- Damp caused by condensation inside the building
If you’re not sure, just ring 01277 525 020 or send photos by email and we will give you a straight answer.

What affects the price in Richmond upon Thames
We price every job individually. The main factors are:
- How much existing material needs removing
- Travel to remote or island sites
- Induction, permit and paperwork requirements
- Working within restricted access windows
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Sending details for a quote
We can often quote from photos and a few details. Please tell us:
- Whether an asbestos survey exists
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- Specification clauses that apply
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Facade sealing in Richmond upon Thames: the local picture
Richmond upon Thames has plenty of hotels close by, all within 2 miles. Hotel extensions and refits usually 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 Richmond upon Thames. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
Recladding or extending a unit at a site like Kew Retail Park, 1.4 miles to the north-east of Richmond upon Thames, brings panel joints and frame perimeters into the programme. Projects at colleges like Richmond-upon-Thames College, 2.1 miles to the west of Richmond upon Thames, tend to run to term dates, so the mastic is planned tightly. Hospital estates such as West Middlesex Hospital, 1.5 miles to the north-west of Richmond upon Thames, 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.

Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Why act early in Richmond upon Thames
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. All of Greater London is in the ULEZ, and kerbside space in Richmond upon Thames can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
What we need from you
- Let us know about inductions and permits
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance

Advice
Different surfaces, different methods
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use.
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface, often a low-modulus silicone or hybrid.
Richmond upon Thames: questions and answers
Can you work on a hospital site such as West Middlesex Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you take on jobs in Richmond upon Thames where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you run new sealant over the existing bead?
No. Overlaying is a shortcut that peels away quickly. Our method is a full cut-out, cleaning, backing and a new bead.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
