Construction mastic in Upper Winchendon, done properly
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. We work on floor and skirting junctions, cladding and panel joints and sanitary and kitchen joints, and the failures we’re asked to look at most are different trades sealing to different standards and old sealant on a refurbishment that needs stripping before new work. One point of contact handles commercial sealant work in Upper Winchendon from the first photos to the final walk-round, whether it’s one building or several.
Sites around smaller places like Upper Winchendon can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Work for main contractors and building owners
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Why it’s worth doing now in Upper Winchendon
Sealing over damaged or contaminated new joints might save a day. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. Damaged joints are removed and resealed from clean faces. Around Upper Winchendon, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why choose Mastic Doctor in Upper Winchendon
- Joints cleaned back to sound surfaces
- Colour agreed before work starts

- RAL and finish matching where the product range allows

General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Your questions answered
Is Upper Winchendon too small for you to travel to?
Not at all. Upper Winchendon is within our area. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
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. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you guarantee new-build sealant work?
Each package is backed by a 12-month guarantee. We carry five million pounds of public liability insurance.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
New build and refits around Upper Winchendon
Upper Winchendon is about 42 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Upper Winchendon is in the South East, one of the UK’s drier regions. 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.
Older buildings in the area around Upper Winchendon, such as Waddesdon Manor, 1.6 miles to the north-west of Upper Winchendon, need care when sealed: the product has to suit soft or historic materials. On a campus such as University Campus Aylesbury Vale, 4.8 miles to the east of Upper Winchendon, new teaching buildings and residences are normally built and refurbished around the academic year.
Upper Winchendon is about 5 miles west of Aylesbury, in Buckinghamshire. Anywhere in HP18, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Buckinghamshire coverage takes in 308 places. Oxford is covered too, some 14 miles away.

What we’re called out for in Upper Winchendon
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Most enquiries start with one or more of the following:
- Sanitary sealant damaged by following trades
- Early adhesion failures on new external joints
- Window and door perimeters that won’t pass inspection
- Failed sealant in an existing building being refurbished
Extensions at sites like St John's Hospital (to the south-east of Upper Winchendon) normally sit beside working departments, and the mastic follows strict access rules.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- How they’ll work around occupants
- Who will actually carry out the work
- The terms of the workmanship guarantee
