Our commercial sealant contractors service in HP23
Mastic Doctor has been sealing joints for businesses and contractors since 2005: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. We work on washrooms and tea points, movement joints in walls and floors and floor and threshold joints, and the usual reasons a site gets in touch are window and door perimeter joints that have cracked open and untidy joints in a reception, shop floor or lobby.
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it.
- Site photographs, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- Completed areas are signed off with you under our 12-month guarantee.
Pricing in HP23
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

Commercial premises across HP23
In HP23, much commercial sealant work follows refits in shops, offices and hotels in places such as Tring, Wigginton and Wilstone. Visible joints call for a matched colour and a clean tooled finish.
All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, and every job in HP23 starts with access, parking and site rules.
Tring: For tenants and agents on sites such as Silk Mill Business Park, less than half a mile north-east of Tring, office fit-outs, reception joints and window perimeters are the usual sealant work. Occupiers with premises at both Silk Mill Business Park and Icknield Way Industrial Estate could have the sealant at each handled under one quote.
When to bring in a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Broken glass or blown double-glazed units
- A dripping trap, valve or pipe behind a fitting
- Roof leaks that only look like a joint problem
Aftercare for building managers
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep washroom and kitchen extraction working
- Ask fit-out and M&E contractors to report any sealant they disturb
- On pre-2000 buildings, share the asbestos information before work starts
- Keep a record of which joints were resealed and when
Brief your cleaning team on the joints that have been resealed. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
Sealant installed at the same time normally fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We will tell you which sealant joints need doing first and which can wait.
Surface by surface
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it.
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.
Why it fails
When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
Look out for the following:
- External beads that have gone brittle and cracked
- Window and door perimeter joints that have cracked open
- Gaps behind commercial kitchen worktops and sinks
- Wall and floor joints that have lost their seal
Your questions answered
How do you keep disruption to occupiers down?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
Do you work directly for building managers?
Yes. FMs, managing agents and landlords are among our regular clients as well as contractors. Tell us how you issue work and we’ll fit in.
Can you supply RAMS and insurance details?
Send your site requirements with the enquiry, and we’ll confirm the RAMS, insurance and CSCS details with the quote. For older buildings we’ll ask for the asbestos register, plus your site induction rules.
Can weather delay the job?
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.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
