Different surfaces, different methods
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.
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, as the specification sets out.
Facade sealing in Cobham
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, but not always. We will tell you if we think the leak is coming from somewhere sealant won’t fix. Site teams most often ask us about gaps between rainscreen or cladding panels and damp patches beside frames after rain, across perimeter joints where frames meet the structure, cladding panel joints and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, in Cobham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a smaller place such as Cobham, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

On site: what to expect
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Work in places the size of Cobham is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- 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.
- 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 what induction or permit system the site runs
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use

Facades, frames and programmes in Cobham
Cobham is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. Cobham is about 17 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
New wings at hospitals like Cobham Community Hospital and Health Centre (to the west of Cobham) bring long runs of window and panel joints to seal. Historic houses such as The Homewood (to the north of Cobham) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. Projects at schools like St Andrew's CofE Primary School work to term dates, so mastic is programmed tightly.
Cobham is about 6 miles west of Epsom, in Surrey. Looking for facade sealing in Cobham? We can help. We work across 379 places in Surrey. Our London page has more on work in that area.

Commercial clients in Cobham
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Cobham can sit alongside others in a wider programme.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Which sealant the job calls for
- How much existing material needs removing
- Travel to remote or island sites
- Backing rod, priming and other preparation
Access can matter as much as the joints themselves: 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.
Details that help us quote
Whether it’s one area or a whole building, these details speed things up:
- Clear photographs of the problem areas
- The postcode of the building
- Drawings or a marked-up plan, if available
- Whether the building will be occupied during the work
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email drawings and photos.
Questions we’re asked in Cobham
Is Cobham off your patch?
No. Places such as Cobham are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Hersham Place Technology Park, near Cobham?
Yes. We cover Cobham and the area around it, including industrial estates, business parks and retail parks such as Hersham Place Technology Park. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long does a typical visit take?
It depends on the scope, but the work usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.

Why act early in Cobham
Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
