How we handle facade sealing in Cookham
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces. Most enquiries involve perimeter sealant that has split or peeled away and cladding panel joints that have opened up, on cladding panel joints, window and door perimeters and shopfront frames. Facilities teams, main contractors and managing agents in Cookham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions around smaller places like Cookham often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Do you need facade sealing in Cookham?
When the sealant tears down its centre, it has normally been asked to move more than it can. The joint may be too narrow, the bead too thin or the sealant the wrong movement class.
Look out for the following:
- Sealant pulling away from frames or panels
- Water coming in around window frames
- Weathered joints at frame-to-structure perimeters
- Patch repairs that keep failing
School extensions, at buildings such as Cookham Rise Primary School, usually run to the summer holidays, mastic included.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their pre-qualification and accreditations
- What level of public liability insurance do they hold?
How the job changes by surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building, so preparation and product choice matter.
Precast concrete panels
Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported.

From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. If neighbouring businesses or buildings around Cookham need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
- Move anything stored against the joints

New build and refits around Cookham
Rainfall across the South East, Cookham included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. A number of hotels sit less than 2 miles from Cookham. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
New wings at hospitals like Marlow Community Hospital (2.1 miles north-west of Cookham) bring long runs of window and panel joints to seal. Work at a hotel such as King's Arms Hotel, 0.9 miles to the east of Cookham, tends to be programmed around bookings, mastic included.

General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
