What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- A dripping trap, valve or pipe behind a fitting
- Walls or slabs moving more than any sealant can take
- Roof leaks that only look like a joint problem
If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
What we seal
- Washrooms and tea points
- External facade joints
- Floor and threshold joints
- Window and door perimeters
- Kitchen worktops and splashbacks
- Movement joints in walls and floors
Commercial sealant contractors in Windmill Hill, done properly
On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. If you have layers of sealant, all of them failing and water staining near frames, panels or ceilings, we can help, whatever the surface. Looking for mastic applicators who cover Windmill Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Occupied buildings in Windmill Hill need the work phased: washrooms in turn, floors in sections and entrances kept open.
Small businesses near places like Windmill Hill frequently occupy converted farm buildings. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.
Our workmanship is guaranteed for 12 months, in Windmill Hill 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 affects the price in Windmill Hill
Before we quote, we look at:
- Whether the work must be split into stages
- Distance, for remote addresses
- Any access equipment needed
- How much existing material needs removing
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
The more we know, the firmer the quote. When you get in touch, include:
- The asbestos register, for older buildings
- Your programme or deadline
- The type of building and who uses it
- The postcode of the building
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or email the details over with what you know.
Looking after the joints
After handover, a little attention goes a long way:
- Don’t let cleaning or traffic back on before the cure time is up
- Check the asbestos register before anyone disturbs old sealant in an older building
- Check sealant as part of routine building inspections
- Keep a record of which joints were resealed and when
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, especially on exposed elevations and in washrooms. If anything looks wrong, call the office on 01277 525 020 or send details through our quote form with a photo.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to.
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we will plan around them, phasing areas so the shop floor stays usable.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal.

Advice
FAQs: Windmill Hill
Will our hotel in Windmill Hill need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Is Windmill Hill too far out for you?
Not at all. Windmill Hill 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.
Does commercial sealant work come with a guarantee?
It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
