Need construction mastic in Fulham?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

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.

About our construction mastic in Fulham

Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, whatever the size of the scheme. Most enquiries involve sealant knocked or painted over by other trades and failed sealant in an existing building being refurbished, across floor and skirting junctions, cladding and panel joints and internal decorators’ caulk. Whether you call it commercial sealant work, mastic application or joint sealing, in Fulham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

The ULEZ covers the whole of Greater London, so contractors’ vehicles on a job in Fulham must meet its standards or pay the daily charge. Alongside that, sites typically need booked deliveries and a plan for where materials go.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Oversized gaps that need packing or adjustment by others
  • Joint design decisions that belong to the architect or engineer
  • Deciding which fire-stopping product a penetration needs

If in doubt, ring 01277 525 020 or email the details over and we will say what we think before you book.

Surfaces we seal

  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Cladding and panel joints
  • Window and door perimeters
  • Internal decorators’ caulk
  • Floor and skirting junctions

Contractors’ notes for Fulham

A good number of hotels sit less than 2 miles from Fulham. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included. As part of Greater London, Fulham is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in.

Work at a hotel such as Hotel Lily, 0.7 miles north-east of Fulham, tends to be programmed around bookings, mastic included. When a college such as St Mellitus Theological College, 1.3 miles to the north-east of Fulham, builds or refurbishes, the mastic package normally has to fit around students and staff. New units and refits on sites such as Hurlingham Business Park, 1 mile south-east of Fulham, need their panel and perimeter joints sealed to the specification.

Fulham is about 2 miles south of Kensington, in Greater London. Anywhere in SW6, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Fulham is one of 764 places in Greater London on our list for mastic packages.

Business premises anywhere in SW6, W6 and W14 are within our area for mastic packages. Buildings on Lampeter Square, Fulham High Street and Hurlingham Square are within our area. Fulham sits on or close to the A219 and A304. We also cover West Kensington (1 mile north), North End (1 mile north), Putney (1 mile south-west), Brook Green (1 mile north-west) and Hammersmith (2 miles north-west). A short drive away, we cover London (5 miles east), City of Westminster (3 miles north-east), Marylebone (4 miles north-east), St Pancras (5 miles north-east), Shoreditch (6 miles north-east) and Walthamstow (11 miles north-east).

Looking after the joints

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Don’t schedule sealing before decorators and flooring are done
  • Get the mastic subcontractor involved early in the programme
  • Keep finished joints away from paint, plaster and scrapers
  • Allow flexibility for external sealing in damp or cold weather

Once an area is sealed, protect it from following trades. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked.

Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.

Common questions from Fulham clients

Is a hospital such as Charing Cross Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Could you schedule work at a campus like BIMM University for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

What joints do you seal on a new build?

The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.

Can you send site paperwork?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Can you seal external joints in wet or cold weather?

Outside, the joint has to be dry and the temperature within the product’s limits. Damp, frost or condensation on frames can stop work.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. In Fulham, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. First we look at the scope on site or from drawings.
  2. A fixed quote sets out scope, products and phasing.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. We seal plot by plot or floor by floor in line with the programme.
  5. Problems we find, such as oversized gaps, are raised right away.
  6. Final snagging is completed and the 12-month guarantee applies.

Preparing the site

  • Make sure the joints can be reached
  • Share your working hours and any access restrictions
  • Confirm the product named in the specification

Related advice

Different surfaces, different methods

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. The sealant is a kitchen-grade product.

Snagging before handover

The last pass before handover is where mastic snags are cleared. Snags are cleared room by room.

How the quote is worked out

These are the things that shape the price:

  • Removal of failed or old sealant
  • Distance, for remote addresses
  • Any access equipment needed
  • Site requirements such as inductions and permits

Pricing mastic packages depends on quantities, condition and access. Ask us for a fixed quote.

Sending details for a quote

It doesn’t need to be a full survey. These details are enough to start:

  • Where the site is, with the postcode
  • The product your specification calls for
  • Clear photos of the problem areas
  • What the building is and how it’s used

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
