Facade sealing for Egham sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Parking and loading for town-centre jobs in Egham are worth mentioning when you send details. On estates and business parks it’s typically simpler.
- 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.
- We walk the finished joints with you before handing over.
Preparing the site
- Share your working hours and any access restrictions
- Flag any permit to work we will need
- Clear stock, furniture or equipment away from the joints

Advice
About our facade sealing in Egham
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on commercial buildings in Egham. Where sealant is the specified fix, we also take on coping and flashing joints. The enquiries we see most involve failed sealant on precast panel joints and air leaks through failed facade joints, on shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints. Looking for mastic applicators who cover Egham? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Many towns of Egham’s size have older buildings being converted or extended, so new windows and cladding meet old masonry. Getting the product and primer right for both faces is what keeps those joints sound.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

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.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.

For managing agents and facilities managers
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Egham can form part of a wider programme across Surrey.
Egham: questions and answers
Do you take on work at healthcare sites like Ashford Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you plan work around the academic year at somewhere like Royal Holloway University?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
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 and the joint cleaned back to sound material. That is what makes the new joint last.
Maintenance after handover
Once the work is signed off, a little attention goes a long way:
- Inspect facade joints on a regular cycle
- Share access with other external trades
- Keep pressure washers away from fresh sealant
- Avoid patch repairs on failed facade joints
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.

Surface by surface
Render and coated surfaces
Paintable sealants exist for joints that will be coated. The choice depends on the specification and finish.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.
Building and refurbishing in Egham
Central London is about 20 miles from Egham. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Egham sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
Hotels like The Runnymede Hotel on Thames (0.7 miles north-east of Egham) rarely close for long, so refurbishment mastic is phased floor by floor. When a college such as Strode's College, less than half a mile to the north-west of Egham, builds or refurbishes, the mastic package typically has to fit around students and staff. On a campus such as Royal Holloway University, 0.8 miles west of Egham, new teaching buildings and residences are normally built and refurbished around the academic year.
