Construction mastic in Dadford, done properly
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. We work on sanitary and kitchen joints, internal decorators’ caulk and window and door perimeters, and what we’re called in for most is sealant knocked or painted over by other trades and oversized or tapered gaps around new frames. For commercial sealant work in Dadford, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Conversions of older rural buildings near smaller places such as Dadford 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 usually what’s needed.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Sites and facades in and around Dadford
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager. At about 55 miles from central London, Dadford is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
University estates such as University of Buckingham (3.8 miles south-east of Dadford) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. Older buildings in the area around Dadford, such as Stowe House, 0.8 miles south-east of Dadford, need care when sealed: the product has to suit soft or historic materials. Recladding or extending a unit at a site like Silverstone Business Park (2.2 miles north of Dadford) brings panel joints and frame perimeters into the programme.

How the quote is worked out
Quotes vary with the job. It mainly depends on:

- How much existing material needs removing
There’s no price list, since every building and every scope is different. Call for a quote.

Your questions answered
Can you work at a site such as Silverstone Business Park, by Dadford?
Yes. We cover Dadford and the area around it, including industrial estates, business parks and retail parks such as Silverstone Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is a hospital such as Buckingham Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Can you seal external joints in wet or cold weather?
Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
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.
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.
Why act early in Dadford
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. We cut out and redo the joint properly. For buildings around smaller places like Dadford, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Don’t force external sealing on a damp or frosty day
- Keep product details for future maintenance
- Flag uneven or tapered frame gaps early
- Ask for joint and product checks before the package is urgent
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement while rigid fillers and caulk can crack where movement is larger. If that happens, let us know.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure so packing or adjustment by the installer comes first. We raise them during our first walk of the area.
How the job changes by surface
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted.
Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or two on a small fit-out and several weeks on a large multi-storey package, and our waste is bagged and taken away as we go. Smaller jobs around Dadford can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
