Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Diagnose, treat, sign off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Jobs near Isbister are often grouped with others in the same area. Tell us how flexible your dates are.
- First we review photos, 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.
- 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.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Have the specification and drawings to hand
- Agree which areas must stay open

Facade sealing for commercial buildings in Isbister
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. If you are dealing with air leaks through failed facade joints and failed sealant on precast panel joints, we can put it right, whatever the surface. A single leaking joint is often how a building in Isbister first comes to us: we look at the rest while we are there and tell you what we find.
For a site around Isbister, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photographs let us bring the right sealants, primers and backing rod first time.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why deal with it now?
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Renewing every failing joint on one visit is the sensible approach for a place like Isbister. Send photographs and we will quote for everything together.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Questions about Isbister
Can you work to our programme on a site in or near Isbister?
Yes, we work to the programme and the sequence the site sets. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can being near the sea in Isbister affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you find out why a window is leaking?
Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we will tell you which.
Do you work in Isbister?
Yes. Isbister is in our area. To discuss a job, phone 01277 525 020 or email drawings and photos.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How do I request a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Facade sealing around Isbister: points for this area
With the shore within about 1 mile, Isbister counts as a coastal location. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. For an island location such as Isbister, work is planned around ferry crossings and the weather. Everything for the package travels with us, so drawings and quantities matter.
Sites around Isbister get mastic sealed to the drawings and the programme, nothing improvised. Around Isbister, as anywhere, a facade joint depends on its sizing, backing rod and preparation.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Providing access systems for the work
- Replacing glass or failed glazing units
- Joints too narrow for the movement they take, which need redesign
If you’re not sure, just phone 01277 525 020 or email the details over and we will give you a straight answer.
What we seal
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Coping and flashing joints
- Shopfront frames
- Stone and brick facade joints
- Cladding panel joints
After the work
For the best life from the joints:
- Note when each elevation was last resealed
- Keep sills, gutters and drainage paths clear
- Brief window cleaners about newly sealed joints
- Add perimeter sealant to planned maintenance checks
Blocked sills and gutters push water at the joints. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
