About our mastic sealing in Upper Horsebridge

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. Most enquiries involve estate-wide sealant that is simply worn out and a mix of products and colours from past repairs, across window and door perimeters on blocks, balcony and threshold joints and external wall and movement joints. For commercial sealant work in Upper Horsebridge, you deal with one contact from quote to sign-off, whether it’s one building or several.

In a smaller place such as Upper Horsebridge, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. Their window perimeters and external joints need renewing as the mastic ages.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. What matters most for a job in Upper Horsebridge is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. First we look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

What we need from you

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • For older buildings, check the asbestos register before work

Advice

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

How the quote is worked out

To price the job, we consider:

  • Working within restricted access windows
  • How much there is to seal
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Sending details for a quote

To price the job accurately, we need to understand the site. Send us:

  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email drawings and photos.

Mastic sealing in Upper Horsebridge: the local picture

Upper Horsebridge sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 46 miles from Upper Horsebridge. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate.

If you own or manage units on a site such as Crown Close Industrial Estate (1.2 miles south of Upper Horsebridge), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Blocks of flats and mixed-use buildings often cluster around stations such as Polegate station (3.9 miles south of Upper Horsebridge) and their window and balcony mastic tends to age at the same rate across a building. If your remit includes a building such as Hawkes Farm Academy, frame and door mastic can be programmed for the holidays.

Upper Horsebridge is about 7 miles north of Eastbourne, in East Sussex. Anywhere in BN27, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 308 places in East Sussex. Our Brighton page has more on work in that area.

Your questions answered

Can you quote for a block close to Polegate station?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

Is a smaller place like Upper Horsebridge outside your area?

Not at all. Upper Horsebridge 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.

Do you guarantee the mastic work?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

How do you reach windows on upper floors?

Every block is different. How upper joints are reached is agreed before work is booked so there are no surprises.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

Different surfaces, different methods

Communal areas

Low-level communal joints get damaged more than most, so they often need renewing sooner.

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. Suspect material is tested before work continues.

Aftercare for building managers

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

  • Plan resealing building by building rather than complaint by complaint
  • Ask residents or tenants to report leaks and draughts early
  • Prioritise elevations facing the weather
  • Include mastic in your cyclical inspections

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing.

Honest limits

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks through the frame itself rather than the perimeter
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Glazing that needs replacing

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.
