Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Tell staff and tenants when we will be in
- Share your working hours and any access restrictions
- Let us know about inductions and permits

Advice
Facade sealing for commercial buildings in Uxbridge
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. If you are dealing with discoloured or dirty facade joints and leaks at window and door perimeters, we can help. For commercial sealant work in Uxbridge, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Work we carry out in Greater London comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or use the quote form and we’ll come back to it.

Other services in Uxbridge
What we are called out for in Uxbridge
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Things that usually lead to an enquiry:
- Leaks at window and door perimeters
- Previous reseals run over old sealant
- Unsightly perimeter sealant on a visible elevation
- Perimeter sealant that has split or peeled away
For contractors on a campus like Brunel University of London, 0.6 miles south of Uxbridge, facade and perimeter sealing has to fit around students and term dates.
What to look for in a quote
- The named product and why it was chosen
- Whether their applicators hold CSCS cards
- What site paperwork they can supply
- Their plan for phasing and protecting the area
Quoting for work in Uxbridge
The price varies from site to site. Expect it to depend on:
- Whether the work must be split into stages
- Joint width, depth and condition
- Travel to remote or island sites
- Whether old sealant has to be cut out first
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Sending details for a quote
To price the job accurately, we need to understand the site. Send us:
- Any dates the work must fit around
- Drawings or a marked-up plan, if available
- Any specification or named product
- A wide shot and a close-up of the area
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
For managing agents and facilities managers
CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Uxbridge: questions and answers
Could you schedule work at a campus like Brunel University of London for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What type of sealant goes on window perimeters?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
How the job changes by surface
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.
Contractors’ notes for Uxbridge
There are several hotels within about 2 miles of Uxbridge. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. As part of Greater London, Uxbridge is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
On a healthcare site such as Hillingdon Hospital, 1.2 miles to the south-east of Uxbridge, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. New units and refits on sites such as Cowley Business Park (0.6 miles south-west of Uxbridge) need their panel and perimeter joints sealed to the specification.
Uxbridge is about 3 miles north-west of Hayes, in Greater London. We send applicators to Uxbridge for facade joints. Our Greater London coverage takes in 764 places. There’s a separate page for London, about 17 miles away.
