Why it’s worth doing now in Donnington
Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Around Donnington, it’s better to renew all the failing joints at once. Send photographs of each area and we will quote for the lot.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Facade sealing in Donnington, done properly
We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters, using sealants classified for facade or glazing use. Site teams most often ask us about gaps between rainscreen or cladding panels and facade joints cracked through the middle, across window and door perimeters, perimeter joints where frames meet the structure and shopfront frames. A single leaking joint is often how a building in Donnington first comes to us: we look at the rest while we’re there and tell you what we find.
Sites around smaller places like Donnington can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions about Donnington
Our building in Donnington is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Can you work around term dates at a campus such as University of Chichester?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can you work on upper floors?
That varies with the building and the access on offer. When you give us a call on 01277 525 020 or email us, describe the access.
How a job runs
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. If others near Donnington need work, visits can be combined. You’ll have a fixed quote before work starts.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Getting the site ready

Advice
Quoting for work in Donnington
To price the job, we consider:
- Whether old sealant has to be cut out first
- Distance, for remote addresses
- Any access equipment needed
- The size and state of each joint
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- Any dates the work must fit around
- Whether the building will be occupied during the work
- How the joints are reached, and at what height

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Inspect facade joints on a regular cycle
- Keep sills, gutters and drainage paths clear
- Keep pressure washers away from fresh sealant
- Check the asbestos register before old mastic is disturbed
Include facade joints in your planned maintenance inspections. Signs to look for are cracking, edges lifting, chalking and stiffness; record the locations.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.
Different surfaces, different methods
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.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
Sites and facades in and around Donnington
Donnington is within about 3 miles of the coast. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so we check the specified product suits the exposure before the first bead. Central London is about 56 miles from Donnington. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
University estates such as University of Chichester, 2.6 miles to the north of Donnington, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Units on estates such as City Business Park (1.6 miles north of Donnington) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Common problems we fix in Donnington
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, so the new bead peels away within a season or two.
Common reasons buildings call us in:
- Previous reseals run over old sealant
- Old perimeter mastic that has dried out
- Failed sealant on precast panel joints
- Damp patches beside frames after rain
Hotel extensions and refits, at places such as Crouchers Hotel, 0.6 miles west of Donnington, typically run between busy periods, so the sealing is squeezed into short windows.
