Mastic sealing for businesses in The Moor

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

Mastic sealing in The Moor, done properly

On a residential block, the work happens around people’s lives. Dates, areas and the order of work are agreed with you in advance so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. We work on balcony and threshold joints, window and door perimeters on blocks and communal kitchens and washrooms, and what we are called in for most is cracked, hardened mastic round windows on a block and mastic failing across several blocks on an estate. Whoever orders the work in The Moor, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like The Moor, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Mastic sealing around The Moor: what changes locally

The Moor is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first. The Moor lies roughly 41 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.

Property owners at sites such as Hawkhurst Station Business Park (to the north of The Moor) can have mastic renewed between lettings. Churches, halls and community buildings such as Church of St Laurence are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

The Moor is about 12 miles north of Hastings, in Kent. Commercial clients in The Moor can call on us for mastic joints. Across Kent, 931 places are covered, including The Moor. Our Brighton page has more on work in that area, about 31 miles away.

If you need mastic sealing in TN18, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Questions we’re asked in The Moor

Is The Moor off your patch?

Not at all. The Moor is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Does your area include sites such as Hawkhurst Station Business Park, near The Moor?

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

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What paperwork can you provide?

Our credentials include CHAS, Constructionline and public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Glazing that needs replacing
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Leaks through the frame itself rather than the perimeter

Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly before you book.

Joints and surfaces we work on

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

Signs you need mastic sealing in The Moor

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits and fails early.

Site and facilities staff are often the first to spot these:

  • Cracked, hardened mastic round windows on a block
  • Failed external movement joints
  • The same joint failures repeated across a portfolio
  • Water getting in round frames after rain

Schools and community buildings such as Marlborough House School need frame and external mastic kept sound like any building.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Their pre-qualification and accreditations
  • Proof of insurance
  • Who will actually carry out the work

How to choose a sealant contractor

Leave it or put it right?

Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure and less choice about when. Halls, stores and units around places like The Moor may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why us?

  • 12 months’ guarantee on every job
  • CSCS-carded applicators
  • Old sealant cut out, never sealed over
  • Fixed quotes based on photographs, drawings or a visit

Read our cost guide or our accreditations.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near The Moor 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. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Send asbestos survey details if the building is pre-2000
  • Agree which areas must stay open

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
