Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Diagnose, treat, sign off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. If others near Badgers Mount need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we look at the mastic on each building and note what needs replacing.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Getting the site ready

  • Share your working hours and any access restrictions

Mastic sealing for commercial buildings in Badgers Mount

Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. If you’re dealing with the same joint failures repeated across a portfolio and damaged joints in communal entrances and corridors, we can help, whatever the surface. Looking for mastic applicators who cover Badgers Mount? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

For owners with a single building near Badgers Mount, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Which sealant the job calls for
  • The size and state of each joint
  • Quantities, in metres or numbers
  • How accessible the joints are

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Before you send an enquiry

Whether it’s one area or a whole building, the same details help:

  • Specification clauses that apply
  • Whether the building will be occupied during the work
  • The postcode of the building
  • How the joints are reached, and at what height

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What we are called out for in Badgers Mount

Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. We will tell you if the joint edges need repairing before resealing.

Typical triggers for a call:

  • Communal area joints that look neglected
  • A mix of products and colours from past repairs
  • Estate-wide sealant that is simply worn out
  • No planned programme for sealant

For a school such as Halstead Community Primary School, perimeter mastic on windows and doors is a holiday job.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • Will failed sealant be removed rather than covered?
  • Health and safety accreditation such as CHAS
  • The terms of the workmanship guarantee

Our contractor checklist

Surface by surface

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent and easier to manage.

Your questions answered

Can you work at a site such as North Downs Business Park, by Badgers Mount?

Yes. Our area takes in Badgers Mount and its surroundings, with estates and business parks such as North Downs Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is Badgers Mount too far out for you?

No. Places such as Badgers Mount are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Include photos or drawings if you have them.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

How many days will you need on site?

It depends on the scope, but the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
