Your questions answered
Is a smaller place like Middle Claydon outside your area?
Not at all. Middle Claydon is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Could you schedule work at a campus like University of Buckingham for the vacation?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Do you do fire-rated sealing on new builds?
We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. If the detail calls for collars, wraps or batts instead, we’ll tell you.
How do you work with the site programme?
Our work is sequenced around the programme. Areas are sealed as they’re released by the site team and we tell you if something stops an area being sealed.
What joints do you seal on a new build?
External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.
What do you charge?
Each job is quoted on its own details. To get one, ring 01277 525 020 or email the details over.
Construction mastic in Middle Claydon
The specification and the programme set the job. Where the specification names a product, we use it, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. We work on brick and block movement joints, window and door perimeters and cladding and panel joints, and the usual reasons a site gets in touch are frame gaps too wide for sealant alone and caulk cracking where joints are moving more than expected. One point of contact handles commercial sealant work in Middle Claydon from the first photographs to the final walk-round, whether it’s one building or several.
Conversions of older rural buildings near smaller places such as Middle Claydon bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Middle Claydon are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- Sealing follows the programme as areas are released.
- Problems we find, such as oversized gaps, are raised straight away.
- Final snagging is completed and the 12-month guarantee applies.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Let building users know which areas are affected

Advice
Maintenance after handover
To get the most from the new sealant:
- Flag uneven or tapered frame gaps early
- Record the products used in the O&M file
- Share drawings and the specification as soon as possible
- Brief following trades on areas that have been sealed
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later. We can confirm the handover information you need when we quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.
What the job involves on each surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification, with backing rod in deeper gaps.
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies and work only when conditions suit.
What sets the cost
The price varies from site to site. Expect it to depend on:
- Joint width, depth and condition
- Which sealant the job calls for
- Whether the work must be split into stages
- Location, for remote and island sites
A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.
What to include in your enquiry
A good diagnosis starts with the right details. Let us know:
- The site address and postcode
- When you need the work done
- Specification clauses that apply
- A wide shot and a close-up of the area
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email us.
Sites and facades in and around Middle Claydon
Middle Claydon lies roughly 47 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
On a campus such as University of Buckingham, 4.8 miles to the north of Middle Claydon, new teaching buildings and residences are usually built and refurbished around the academic year. For contractors at a school such as East Claydon Church of England School, sealing has to be finished before term starts.
Middle Claydon is about 5 miles south of Buckingham, in Buckinghamshire. Middle Claydon sits inside our coverage and the rest of Buckinghamshire, with the same fixed quotes and 12-month guarantee as everywhere else. Middle Claydon is one of 308 places we cover in Buckinghamshire for mastic packages. Oxford is covered too, around 17 miles from Middle Claydon.

We also cover Botolph Claydon (1 mile south-east), East Claydon (1 mile east), Steeple Claydon (1 mile north-west), Adstock (3 miles north-east) and Padbury (3 miles north) for mastic packages.

When to call us in Middle Claydon
On a live site, contamination is the biggest threat to a new joint. Plaster dust, release agents, protective film residue and damp all stop sealant bonding so faces get cleaned, and primer goes on wherever the maker specifies, even on new work.
Clients typically get in touch after noticing something like this:
- External joints sealed in damp or cold conditions that are now failing
- Mastic snags holding up handover
- Frame perimeters left unsealed or poorly sealed
- Failed sealant in an existing building being refurbished
On a healthcare site such as Buckingham Community Hospital (5.4 miles north of Middle Claydon), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
- Who will actually carry out the work
