How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in Wendover, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies 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.
Before we start on site

Owners, agents and contractors
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Do you need facade sealing in Wendover?
Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.
Things that normally lead to an enquiry:
- Previous reseals run over old sealant
- Failed sealant on precast panel joints
- Failed seals around shopfront and entrance frames
- Leaks at window and door perimeters
When units on a site such as Station Approach Business Park (under half a mile west of Wendover) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

FAQs: Wendover
Is a hospital such as Stoke Mandeville Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Will you plan work around the academic year at somewhere like University Campus Aylesbury Vale?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
What will the job cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
Should maintenance staff do it?
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.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Movement beyond what any sealant can handle
- Installing or repairing glazing systems
- Damaged frames that need replacing
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

Building and refurbishing in Wendover
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. There are several hotels within about 2 miles of Wendover. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
Projects at schools like The John Hampden School work to term dates, so mastic is programmed tightly. Hotels like Vine Tree Hotel (under half a mile south of Wendover) rarely close for long, so refurbishment mastic is phased floor by floor.

Different surfaces, different methods
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, as the specification sets out.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair.
