Sealant specialists in Greenhill
If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Greenhill, the quickest start is to ring 01277 525 020 or send details through our quote form with a list of addresses. We work on washrooms and tea points, movement joints in walls and floors and window and door perimeters, and the usual reasons a site gets in touch are weathered facade sealant that no longer flexes and wall and floor joints that have lost their seal. Most enquiries from Greenhill start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Multi-site clients with buildings in and around Greenhill can put several sites on one programme, so standards and paperwork match across every site.
Buildings in a London area such as Greenhill rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
From enquiry to sign-off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. 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.
- First, details come to us: photographs, drawings or a schedule of the areas.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- Site hours, access windows and the order of areas are agreed before we start.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Agree which areas must stay open
- Explain the parking and delivery arrangements

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Related advice
When to call us in Greenhill
If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. It’s one of the commonest faults we find on earlier work.
Look out for the following:
- Smeared sealant across finishes from a rushed job
- Wall and floor joints that have lost their seal
- Hardened, chalky sealant on south-facing or exposed elevations
- Leaks that seem to come through a sealant line
Refits at hotels like Quality Hotel Hampstead, less than half a mile south-west of Greenhill, bring joints at vanity tops, bars and reception desks that guests see every day.
What your quote should include
- How the joint faces will be prepared and primed
- Whether old or failed sealant will be cut out, not overlaid
- Their plan for phasing and protecting the area
- Whether their applicators hold CSCS cards
Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Faulty windows rather than failed perimeter sealant
- Cracking that needs a structural engineer to look at it
- Suspect materials that need testing and specialist removal
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.
Joints and surfaces we work on
- Washrooms and tea points
- External facade joints
- Movement joints in walls and floors
- Kitchen worktops and splashbacks
- Window and door perimeters
- Floor and threshold joints
Why deal with it now?
Some managers wait for a fit-out before touching the mastic. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Your questions answered
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Will you take on work at estates like Regis Road Business Park, close to Greenhill?
Yes. Our area takes in Greenhill and its surroundings, with estates and business parks such as Regis Road Business Park included. Photos and a short description are enough for a first look.
Can you handle sealant work across several sites?
Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.
Is your work guaranteed?
A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.
What do you need from us to quote?
Start with whatever information is to hand. Questions or a site visit follow where needed.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
