How we handle commercial sealant contractors in Tower Hill
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on movement joints in walls and floors, external facade joints and washrooms and tea points, and what we’re called in for most is a top-up bead over failed sealant, now lifting and wall and floor joints that have lost their seal. Searching for sealant specialists in Tower Hill? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
In Tower Hill, as anywhere, the first joints to go are typically the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.
For managing agents and FMs looking after premises in Tower Hill, access is typically the first question: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
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.

Common problems we fix in Tower Hill
No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. On a busy commercial site several of those pile up at once.
Site and facilities staff are often the first to spot these:
- Earlier reseals applied straight onto the failed bead
- Expansion joints with the sealant torn out
- Gaps behind commercial kitchen worktops and sinks
- Damp patches where an external joint has failed
If you have premises on more than one site, say at Southwark Bridge Business Centre and Princes Court Business Centre, one contractor and one quote can cover both.
Comparing quotes
- Whether old or failed sealant will be cut out, not overlaid
- Which product they’ll use, and why it suits the joint
- The terms of the workmanship guarantee
- Health and safety accreditation such as CHAS

Leave it or put it right?
Putting off a reseal typically moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next, and the bill then involves other trades. Dealing with it while the damage stops at the bead is the cheaper route. In Tower Hill, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Pricing sealant joints depends on quantities, condition and access. Ask us for a fixed quote.

Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Old mastic that tests positive for asbestos
- Roof leaks that only look like a joint problem
- Faulty windows rather than failed perimeter sealant
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

Questions about Tower Hill
Must a hotel around Tower Hill close while you work?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, which many sites require.
Do you take on multi-site sealant work?
Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Is your work guaranteed?
Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations, and a site visit is booked where it helps.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Finished joints are checked with you and handed over with our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Share the asbestos register for older buildings
- Flag any permit to work we’ll need

Advice
For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
