Cole End: questions and answers
Is a hospital such as Saffron Walden Community Hospital (no A&E) somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Shire Hill Industrial Estate, near Cole End?
Yes. Our area takes in Cole End and its surroundings, with estates and business parks such as Shire Hill Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
How do you work with the site programme?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Can you work while the building is occupied?
Usually, yes. We phase the work so most of the building stays in use.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
About our construction mastic in Cole End
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old 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, window and door perimeters and brick and block movement joints, and the usual reasons a site gets in touch are inconsistent sealant finishes from plot to plot and old sealant on a refurbishment that needs stripping before new work. For commercial sealant work in Cole End, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Construction in and around smaller places such as Cole End is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Our workmanship is guaranteed for 12 months, in Cole End as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Glazing units that are cracked or misted
- Frames fitted out of tolerance
- Fire-stopping design or sign-off (that’s for the designer, fire engineer and building control)
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly.
Surfaces we seal
- Window and door perimeters
- Brick and block movement joints
- Floor and skirting junctions
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Cladding and panel joints
Different surfaces, different methods
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move.
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we’ll flag where the detail needs something different. Record requirements are agreed with the quote.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
After the work
Regular inspection catches problems early. Specifically:
- Keep product details for future maintenance
- Keep scrapers and abrasive pads off new beads
- Allow flexibility for external sealing in damp or cold weather
- Share drawings and the specification as soon as possible
After we have sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last. We flag them as soon as we see them.
On site: what to expect
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Rural sites near Cole End may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- We walk the site or review drawings to understand the package.
- You receive a fixed quote covering scope, products and sequence.
