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 where general trades tend to cut corners.
A short, simple internal joint is often within reach of a maintenance team. 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.
Facade sealing in Hayes
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. We work on stone and brick facade joints, window and door perimeters and perimeter joints where frames meet the structure, and the usual reasons a site gets in touch are discoloured or dirty facade joints and perimeter joints where frames meet the structure. For commercial sealant work in Hayes, you deal with one contact from quote to sign-off, whether it’s one building or several.
The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Hayes must meet its standards or pay the daily charge. Alongside that, sites usually need booked deliveries and a plan for where materials go.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Building and refurbishing in Hayes
As part of Greater London, Hayes is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in. Plenty of hotels sit less than 2 miles from Hayes. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Hotel extensions and refits, at places such as Fountain House Hotel, which lies north-east of Hayes, typically run between busy periods, so the sealing is squeezed into short windows. Projects at colleges like Uxbridge College, less than half a mile east of Hayes, tend to run to term dates, so the mastic is planned tightly.
Hayes is about 8 miles east of Slough, in Greater London. Any commercial site in Hayes is covered, whether it’s a single job or part of a planned programme. 764 places across Greater London fall within our area, Hayes among them. Our London page has more on work in that area.

Signs you need facade sealing in Hayes
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, so the new bead peels away within a season or two.
Any of the following is a good reason to get the joints checked over:
- Previous reseals run over old sealant
- Cold air coming in at window perimeters
- Staining on stone next to old sealant
- Water coming in around window frames
Units on estates such as Caxton Trading Estate, 0.5 miles to the south of Hayes, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Will failed sealant be removed rather than covered?
- Will CSCS-carded applicators be on site?
- Whether primer will be used where the manufacturer specifies it
- Health and safety accreditation such as CHAS
Looking after the joints
Regular inspection catches problems early. In particular:
- Inspect facade joints on a regular cycle
- Keep sills, gutters and drainage paths clear
- Report water ingress at frames as soon as it shows
- Keep the sealant details on the building file
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones behind the facade.
Our process
At the end of each section, we remove the tape, clean down and inspect every joint. Where the sealant needs time to cure before use, we tell you and sign the area. Planning a London job such as one in Hayes starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
What we need from you
- Send your site hours and access windows
- Agree which areas must stay open
- Have the specification and drawings to hand

Advice
What happens if it’s left?
Each spell of rain drives water past a failed facade joint. 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. Getting scaffold, permits or access booked in Hayes takes effort, so it makes sense to deal with every failing joint while access is in place.
A quote for facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Questions about Hayes
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Can you work at a site such as Caxton Trading Estate, by Hayes?
Yes, sites like Caxton Trading Estate are within our area, along with the rest of Hayes. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Do you run new sealant over the existing bead?
No. New sealant won’t hold on old sealant, so the old bead is cut away. That is what makes the new joint last.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather. For bigger or phased jobs, we’ll set out a timescale with the quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first. Removal of asbestos isn’t something we do.
How the quote is worked out
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Phasing around occupants
- Which sealant the job calls for
- Quantities, in metres or numbers
- How much existing material needs removing
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote when you’re ready.
What we need to price the job
For an accurate fixed quote, we need to understand the site. Useful things to include:
- The postcode of the building
- Your programme or deadline
- Photos of the joints, close up and from further back
- Approximate linear metres or a joint schedule
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or ring 01277 525 020 or use the quote form to discuss it first.
