About our mastic sealing in Tidebrook

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. If you have open joints in brickwork or panels and damaged joints in communal entrances and corridors, we can put it right. Searching for sealant specialists in Tidebrook? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Rural conversions near places like Tidebrook often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When to call us in Tidebrook

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.

These are often picked up first by site or facilities staff:

  • The same joint failures repeated across a portfolio
  • Draughts at frames across a block
  • Water getting in round frames after rain
  • Failed external movement joints

For agents with blocks near Wadhurst station, 2.4 miles to the north of Tidebrook, a block-wide mastic programme deals with frames, balconies and entrances in one go.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • How the existing material will be dealt with
  • Their public liability cover

Choosing a commercial sealant contractor

Blocks and managed buildings in Tidebrook

At about 36 miles from central London, Tidebrook is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate. Tidebrook sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

Landlords with units on estates such as Durgates Industrial Estate, 2.4 miles to the north-east of Tidebrook, can bring frame, door and external mastic across several units into one programme. For a school such as Uplands Community College, perimeter mastic on windows and doors is a holiday job.

Tidebrook is about 6 miles east of Crowborough, in East Sussex. We send applicators to Tidebrook for mastic joints, handled exactly as we handle every other area. Tidebrook is one of 308 places in East Sussex on our list. Brighton is covered too, around 23 miles from Tidebrook.

Why deal with it now?

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Older rural buildings around Tidebrook move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

What you get with us

  • Specification-led, product-correct work
  • Constructionline member for supplier checks
  • Joints cleaned back to sound surfaces
  • Over 20 years of commercial sealing

Tidebrook: questions and answers

Can you quote for a block close to Wadhurst station?

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

Does your area include sites such as Durgates Industrial Estate, near Tidebrook?

Yes. Our area takes in Tidebrook and its surroundings, with estates and business parks such as Durgates Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.

How do you handle work on occupied blocks?

We plan around people living or working in the building. We agree the programme so you can notify occupiers and communal access is kept open.

How many days will you need on site?

That varies with the scale of the job, but the work usually 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.

Can you reseal a whole block or estate?

We can. Each building is inspected, quoted and scheduled in turn starting wherever is most urgent.

How do you reach windows on upper floors?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we’ll tell you how we’d approach it.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.

Cost factors for mastic joints

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • Removal of failed or old sealant
  • The size and state of each joint
  • Whether the work must be split into stages

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • Any specification or named product
  • Clear photographs of the problem areas
  • Whether an asbestos survey exists
  • When you need the work done

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Leaks from above rather than through a joint
  • Asbestos-containing sealant, which we don’t remove
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)

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

Surfaces we seal

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

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
