Commercial mastic work in Tulse Hill

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. If you are dealing with black mould through washroom sealant that won’t clean off and hardened, chalky sealant on south-facing or exposed elevations, we can put it right. Most enquiries from Tulse Hill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

A lot of what we do in Tulse Hill is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Around Tulse Hill, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks, and our waste is bagged and taken away as we go. In Tulse Hill, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Warn occupants and staff about the work
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • Location, for remote and island sites
  • Working within restricted access windows

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • The type of building and who uses it
  • Any dates the work must fit around
  • The site address and postcode
  • Anything awkward about access or site hours

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

Each new occupier on a park like these tends to refit, from reception to staff kitchen, often in a colour the occupier specifies. A good number of hotels sit less than 2 miles from Tulse Hill. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes.

Industrial estates such as Bessemer Park Industrial Estate, 1 mile to the north of Tulse Hill, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Signs you need commercial sealant contractors in Tulse Hill

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Most enquiries start with something like this:

  • Sanitary sealant that has gone black and patchy
  • Water staining near frames, panels or ceilings
  • Wall and floor joints that have lost their seal
  • Weathered facade sealant that no longer flexes

In hotels such as Leigham Court Hotel, 1 mile south-west of Tulse Hill, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Questions to ask before you appoint anyone

Owners, agents and contractors

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Tulse Hill can form part of a wider programme.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

FAQs: Tulse Hill

Do you take on jobs in Tulse Hill where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough

Do you cover business parks and estates near Tulse Hill, such as Bessemer Park Industrial Estate?

Yes, sites like Bessemer Park Industrial Estate are within our area, along with the rest of Tulse Hill. Send details of the unit and the work through our quote form for a quick quote.

How is commercial sealant work priced?

Send what you have, even a few photos and rough lengths. Questions or a site visit follow where needed.

Do you check for asbestos before removing sealant?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility and removing it isn’t something we do.

What site paperwork can you provide?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

What guarantee do you give on resealing?

A 12-month guarantee covers the workmanship, starting at sign-off. Keeping joints clean and inspected helps them last well beyond that.

How long do sealant joints last?

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.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Water from a services leak rather than a joint

If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think before you book.

Joints and surfaces we work on

  • Floor and threshold joints
  • Movement joints in walls and floors
  • Washrooms and tea points
  • Kitchen worktops and splashbacks
  • External facade joints
  • Window and door perimeters

Doing it in-house

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

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.
