Mastic sealing for businesses in West End

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Mastic sealing for commercial buildings in West End

For blocks and buildings in West End and across Kent, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. The enquiries we see most involve no planned programme for sealant and draughts at frames across a block, across external wall and movement joints, shopfronts below residential blocks and communal kitchens and washrooms. Whether you call it commercial sealant work, mastic application or joint sealing, in West End it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural conversions near places like West End often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What happens if it’s left?

Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. Converted and older buildings near places like West End tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

What you get with us

  • Over 20 years of commercial sealing
  • Our applicators hold CSCS cards
  • A fixed quote before work starts
  • One contact handling all your sites

Take a look at what affects the cost or our accreditations and insurance.

General trades versus a specialist

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

When it isn’t the sealant

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Leaks from above rather than through a joint
  • Broken glass or failed sealed units
  • Asbestos-containing sealant, which we don’t remove

If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.

Joints and surfaces we work on

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

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around West End, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  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.

Before we start on site

  • Point out any areas we must not close
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to phone 01277 525 020 or send photos by email with what you know.

Common questions from West End clients

Is West End too far out for you?

Not at all. West End is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Does the sea air around West End change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Who decides which product is used?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you reseal a whole block or estate?

Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it.

How the quote is worked out

These are the things that shape the price:

  • The total length or number of joints
  • The product specified
  • Distance, for remote addresses
  • Phasing around occupants

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Access details, including height
  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Frames, entrances and external joints in West End

West End lies within about 2 miles of the sea. On buildings near the shore, the side facing the weather typically needs its mastic renewed first, and they deserve more regular inspection. Rainfall across the South East, West End included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

Site managers at schools like Thornden Wood Primary School can fit frame mastic into the summer works. If you own or manage units on a site such as St. Augustine's Business Park, 1.1 miles north-west of West End, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. If you look after a block within reach of Chestfield & Swalecliffe station (1.3 miles north-west of West End), frame and balcony mastic can be renewed on one programme.
