Mastic sealing for businesses in Bromley Green

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

How we handle mastic sealing in Bromley Green

Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. Most enquiries involve damaged joints in communal entrances and corridors and brittle perimeter mastic across a building, across window and door perimeters on blocks, communal entrances and stairwells and balcony and threshold joints. A single leaking joint is often how a building in Bromley Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Owners and agents with buildings around smaller places such as Bromley Green tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Why deal with it now?

Sealing over failed mastic looks tidy for a while. It doesn’t bond and usually fails within a short time. Full removal and proper preparation is what lasts. Around Bromley Green, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why us?

  • CSCS-carded applicators
  • 12 months’ guarantee on every job
  • Colour agreed before work starts
  • Fully insured, including public liability cover

See our cost guide or our accreditations and insurance.

Aftercare for building managers

For the best life from the joints:

  • Encourage occupiers to report problems at frames
  • Keep bins and bikes away from communal door frames
  • Keep a record of when each building was resealed
  • Mention RAMS, insurance or CSCS requirements up front

Our workmanship is covered for 12 months, so report any failure in that time. After that, regular inspection keeps the programme on track.

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.

When to call us in Bromley Green

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Cleaning products add to the wear.

Things that usually lead to an enquiry:

  • No planned programme for sealant
  • Window mastic that has split and shrunk
  • Draught complaints from residents or tenants
  • The same joint failures repeated across a portfolio

For a school such as John Wallis Academy, perimeter mastic on windows and doors is a holiday job.

How to choose a sealant contractor

Our process

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Bromley Green may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Preparing the site

  • Point out any areas we must not close
  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs

Quotes

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

When something else is needed

Honesty saves time and money. Fresh joints won’t solve:

  • Frames that are rotten, warped or broken
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

If you are not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.

Surfaces we seal

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

Questions about Bromley Green

Will you take on work at estates like Bliby Business Centre, close to Bromley Green?

Yes, sites like Bliby Business Centre are within our area, along with the rest of Bromley Green. Photos and a short description are enough for a first look.

Is Bromley Green too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Does the weather affect the work?

Outside, 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.

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
