On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Several jobs near Byfleet can be grouped on one trip. Tell us your site hours and we will plan around them.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- 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.
- 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.
Preparing the site
- Tell us your opening times and when work is allowed
- Explain the parking and delivery arrangements
- Flag any permit to work we will need
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Facade sealing in Byfleet, done properly
Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. We work on stone and brick facade joints, coping and flashing joints and cladding panel joints, and the failures we’re asked to look at most are patch repairs that keep failing and cladding panel joints that have opened up. A single leaking joint is often how a building in Byfleet first comes to us: we look at the rest while we’re there and tell you what we find.
For a contractor on a smaller site near Byfleet, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Byfleet
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead.
Most enquiries start with something like this:
- Facade joints cracked through the middle
- Previous reseals run over old sealant
- Cold air coming in at window perimeters
- Cladding panel joints that have opened up
On a healthcare site such as Cobham Community Hospital and Health Centre, 2.8 miles east of Byfleet, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Questions to ask before you book
- Their pre-qualification and accreditations
- Their public liability cover
- What the guarantee covers, and for how long
- Is the sealant right for the movement and the substrate?
FAQs: Byfleet
Can you take on a job at a hospital such as Cobham Community Hospital and Health Centre?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you take on work at estates like Wey Retail Park, close to Byfleet?
Yes. We cover Byfleet and the area around it, including industrial estates, business parks and retail parks such as Wey Retail Park. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Do we need an asbestos check before resealing?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder, and we’ll ask to see it. Suspect material is left alone until it has been tested.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
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.
Is it okay to overlay old mastic?
No. A bead run over old sealant soon lifts. We remove the failed sealant, clean the faces, set the depth and reseal.
What will the job cost?
There isn’t a price list, because every site is different. With photographs or drawings, we can give you a fixed quote.
When something else is needed
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Joints whose design needs changing by the specifier
- Replacing glass or failed glazing units
- Damaged frames that need replacing
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal
- Coping and flashing joints
- Shopfront frames
- Window and door perimeters
- Stone and brick facade joints
- Cladding panel joints
- Perimeter joints where frames meet the structure
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
Contractors’ notes for Byfleet
Central London is about 20 miles from Byfleet. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team.
For contractors at a school such as St Mary's CofE Controlled Primary School, sealing has to be finished before term starts. For contractors at a college like Brooklands Technical College - Weybridge Campus, 1.7 miles north of Byfleet, perimeters and internal sealant are timed for the holidays.

Quoting for work in Byfleet
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- How much there is to seal
- The size and state of each joint
- Access and working height
- Whether old sealant has to be cut out first
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
Sending details for a quote
Good information means a firmer quote. Helpful details to send:
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- The product your specification calls for
- Drawings or a marked-up plan, if available
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Check the asbestos register before old mastic is disturbed
- Record the product and colour used on each elevation
- Don’t wait for a second leak before calling
- Walk the elevations once or twice a year
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly using a matching sealant.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
