What we’re called out for in Newtown
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building, and cracks or adhesion loss follow.
If one of these sounds familiar, it’s time for a closer look:
- Failed seals around shopfront and entrance frames
- Discoloured or dirty facade joints
- Cladding panel joints that have opened up
- Hard, chalky sealant that no longer flexes
Recladding or extending a unit at a site like Suttons Business Park (under half a mile north-east of Newtown) brings panel joints and frame perimeters into the programme.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with
- Who will actually carry out the work
- Will RAMS and insurance details be available?
How we handle facade sealing in Newtown
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Where sealant is the specified fix, we also take on coping and flashing joints. If you are dealing with perimeter joints where frames meet the structure and hard, chalky sealant that no longer flexes, we can put it right, on cladding panel joints, shopfront frames and stone and brick facade joints alike. Searching for sealant specialists in Newtown? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Around places like Newtown, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Don’t wait for a second leak before calling
- Add perimeter sealant to planned maintenance checks
- Ask about asbestos in pre-2000 mastic
- Keep the sealant details on the building file
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.

How a job runs
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 before the next one starts. For a site in Newtown, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Preparing the site
- Tell us your opening times and when work is allowed

How the quote is worked out
These are the things that shape the price:
- The site’s rules and procedures
- Location, for remote and island sites
- Joint width, depth and condition
- Access and working height
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Your programme or deadline
- Access details, including height
- Whether the building will be occupied during the work
- The product your specification calls for
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Leave it or put it right?
Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice. For buildings in places like Newtown, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
A quote for facade joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Different surfaces, different methods
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported before sealing.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish.
Facade sealing around Newtown: how the place shapes the job
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. There are a good number of hotels within about 2 miles of Newtown. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Building work at universities like University of Reading (to the south-west of Newtown) is often timed for the summer, mastic included. When a college such as Reading College, less than half a mile west of Newtown, builds or refurbishes, the mastic package normally has to fit around students and staff.
