Mastic sealing for Birch Hill sites

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

Mastic sealing in Birch Hill

Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints, and the failures we are asked to look at most are estate-wide sealant that is simply worn out and window mastic that has split and shrunk. A single leaking joint is often how a building in Birch Hill first comes to us: we look at the rest while we’re there and tell you what we find.

Older buildings and conversions around places like Birch Hill mix old masonry with newer frames. Perimeter joints need a sealant that suits both frame and masonry.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

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.

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a site in Birch Hill, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  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. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

FAQs: Birch Hill

Is Bracknell Enterprise Centre, near Birch Hill, within your area?

Yes. We cover Birch Hill and the area around it, including industrial estates, business parks and retail parks such as Bracknell Enterprise Centre. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.

Can you quote for a block close to Bracknell station?

Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Is asbestos a concern with old mastic?

Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

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

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What the job involves on each surface

Communal areas

Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Tidy, sound joints keep them looking cared for.

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. We plan around the site hours and access windows you give us.

Blocks and managed buildings in Birch Hill

Bracknell, one of the planned towns of the twentieth century, takes in or adjoins Birch Hill. Estates from the same phase usually have mastic of the same age, so owners and associations can deal with it block by block. Birch Hill is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

Blocks of flats and mixed-use buildings often cluster around stations such as Bracknell station (to the north of Birch Hill) and their window and balcony mastic tends to age at the same rate across a building. Landlords with units on estates such as Bracknell Enterprise Centre (1.8 miles north of Birch Hill) can bring frame, door and external mastic across several units into one programme. Churches, halls and community buildings such as St Michael and St Mary Magdalene's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Masonry that has broken away beside the joint
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Glazing that needs replacing

If you’re not sure, just give us a call on 01277 525 020 or email us and we’ll give you a straight answer.

What we need to price the job
