Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lisson Grove can sit alongside others in a wider programme.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

Coloured sealant in Lisson Grove, done properly

Coloured sealant work ranges from a new shop fit to replacing failed joints on an existing building on sites in Lisson Grove. When replacing old joints, the new colour normally has to match what’s already there. If you have smeared sealant on stone or joinery and fit-outs with a sealant colour in the specification, we can help, on office fit-out finishes, cladding panels and hotel bathrooms and public areas alike. Whoever orders the work in Lisson Grove, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For managing agents and FMs looking after premises in Lisson Grove, access is normally the first question: loading bay slots, goods lifts, permits to work and somewhere to keep materials. With access agreed, we work through the colour-matched joints a section at a time, keeping disruption to tenants low.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Repairing damaged frames or cladding
  • Finishes that change colour from one area to another
  • Paint over sealant on joints that move too much

If in doubt, phone 01277 525 020 or email us and we will say what we think.

What we seal

  • Cladding panels
  • Shop-fit joinery and counters
  • Hotel bathrooms and public areas
  • Powder-coated and anodised frames
  • Office fit-out finishes
  • Natural stone and brick

What affects the price in Lisson Grove

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Sending details for a quote

However big the job, the same details help:

  • The product your specification calls for
  • Access details, including height
  • When you need the work done
  • A wide shot and a close-up of the area

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or email us with what you know.

Why deal with it now?

Resealing a full run gives a consistent colour. Piecemeal repairs over several years tend to drift in colour, so a planned reseal often looks better value. In Lisson Grove, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

Pricing colour-matched joints depends on quantities, condition and access. Call for a quote.

Questions we are asked in Lisson Grove

Is The Quadrant Business Centre, near Lisson Grove, within your area?

Yes, sites like The Quadrant Business Centre are within our area, along with the rest of Lisson Grove. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

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. The ULEZ covers the whole of Greater London, which we allow for

Do you take on colour-matched sealant for shop fits and multi-site roll-outs?

Yes. Tell us the product and colour reference and we will confirm availability for a quick quote. Tell us your site hours and access windows and we’ll plan around them.

Do you have public liability insurance?

Yes. Mastic Doctor is fully insured, public liability included.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

On site: what to expect

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a day for a modest shop fit, and longer for a full building or several floors. Planning a London job such as one in Lisson Grove starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. We start with photographs, drawings or a visit to see the finishes.
  2. Colour options from the specified product’s range are shared with you.
  3. Tell us your site hours and access windows and we will plan around them.
  4. Joints are prepared, primed where specified and backed.
  5. The agreed colour is installed and tooled neatly.

Before we start on site

  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Advice

Looking after the joints

For the best life from the joints:

  • Insist on the agreed colour for any repair
  • Brief cleaners about newly sealed joints
  • Agree the sealant colour early and write it into the specification
  • Avoid piecemeal repairs on coloured joints

Clean coloured joints with mild, non-abrasive products. Strong solvents and abrasive pads can dull or mark the surface.

Ask for a trial bead on high-profile areas. Seeing the cured colour in place avoids surprises.

Working on commercial sites near Lisson Grove

Lisson Grove has at least three named business or industrial parks inside a 3-mile radius. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. There are plenty of hotels within about 2 miles of Lisson Grove. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme, with rooms done in turn while the rest stay let.

For tenants and agents on sites such as The Quadrant Business Centre, 1.9 miles to the north-west of Lisson Grove, office fit-outs, reception joints and window perimeters are the usual sealant work. Shopping centres and retail parks such as O2 Centre (1.6 miles north of Lisson Grove) see a steady turnover of shop fits, each leaving joints where colour and finish matter. Offices and shops close to stations such as London Marylebone station, under half a mile east of Lisson Grove, tend to be busy all day, so sealant work is planned around opening hours.
