Mastic sealing for Fairlop sites

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

What we can’t put right

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

  • Water coming in from the roof or rainwater goods
  • Misted or failed double-glazed units
  • Masonry that has broken away beside the joint

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

What we seal

  • Shopfronts below residential blocks
  • Balcony and threshold joints
  • Communal entrances and stairwells
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Window and door perimeters on blocks

Mastic sealing in Fairlop, done properly

For blocks and buildings in Fairlop and across Greater London, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photographs and approximate joint numbers are enough for a quick quote, and site visits can be arranged. Most enquiries involve open joints in brickwork or panels and draught complaints from residents or tenants, across communal kitchens and washrooms, external wall and movement joints and communal entrances and stairwells. Most enquiries from Fairlop start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Across Greater London, Fairlop included, the ULEZ applies, and parking and loading rules differ from street to street. For a block or estate, it helps to know where we can park and stage materials.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Work for main contractors and building owners

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Share your contractor requirements early
  • Look at the sunniest and most exposed elevations first
  • Share the asbestos register when you send details
  • Make mastic part of routine maintenance checks

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Why it’s worth doing now in Fairlop

Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish. Failed sealant in a building in Fairlop can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

Why us?

  • CSCS-carded applicators
  • CHAS accredited contractor
  • Over 20 years of commercial sealing
  • Colours confirmed for the specified product

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Flag any permit to work we will need
  • Send your site hours and access windows

General trades versus a specialist

There’s also the paperwork. 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.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Questions we are asked in Fairlop

Can you quote for a block close to Seven Kings station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Can you work in a London building with booked loading and goods-lift slots?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. You get a fixed quote per building or for the whole job.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How many days will you need on site?

That varies with the scale of the job, though a typical visit typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Can people stay in the building while you reseal?

Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so it can be arranged.
