Mastic sealing across Arborfield

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

Mastic sealing in Arborfield

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on window and door perimeters on blocks, external wall and movement joints and shopfronts below residential blocks, and the failures we are asked to look at most are estate-wide sealant that is simply worn out and movement joints with sealant missing. Whether you call it commercial sealant work, mastic application or joint sealing, in Arborfield it comes down to the same thing: the right product in a properly prepared joint.

Rural conversions near places like Arborfield often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions we’re asked in Arborfield

Is a smaller place like Arborfield outside your area?

No. Places such as Arborfield are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Will you take on a block within reach of Winnersh station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Can you reseal a whole block or estate?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

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.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Do you seal on top of existing sealant?

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

Mastic sealing around Arborfield: points for this area

The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Arborfield lies roughly 36 miles out from central London. 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.

Landlords with units on estates such as Thames Valley Science Park (1.4 miles north-west of Arborfield) can bring frame, door and external mastic across several units into one programme. Student accommodation around universities such as University of Reading - Whiteknights Campus, 2.9 miles north-west of Arborfield, is normally managed block by block, which suits a planned mastic programme.

What sets the cost

Each job is priced on its own details. The main factors are:

  • Any access equipment needed
  • Quantities, in metres or numbers
  • Whether the work must be split into stages
  • The product specified

Pricing mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

What we need to price the job

A few photos plus some basic facts will normally do. Please tell us:

  • The postcode of the building
  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • What the building is and how it’s used

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, phone 01277 525 020 or email a schedule or drawings.

Our process

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. For work around Arborfield, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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 programme is fixed with you, including dates you can pass on to residents or tenants.
  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. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
  • Point out parking and an unloading spot

Related advice

What we’re called out for in Arborfield

Frames, panels and masonry expand and contract through the year, and the sealant takes up that movement. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.

Things that normally lead to an enquiry:

  • Draught complaints from residents or tenants
  • The same joint failures repeated across a portfolio
  • Complaints coming in block by block
  • A mix of products and colours from past repairs

Buildings close to stations like Winnersh station, 2.5 miles north-east of Arborfield, are often flats over shops, with frame mastic to keep sound.

Before you book anyone

  • Their public liability cover
  • Do they follow the manufacturer’s priming guidance?
  • Is the sealant right for the movement and the substrate?
  • Health and safety accreditation such as CHAS

How to choose a sealant contractor

Why deal with it now?

Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Arborfield, rather than one at a time. Send photos of each area and we’ll quote for the lot.

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Why clients in Arborfield choose us

  • Colours chosen to suit frames, cladding or finishes where possible
  • Work to your specification and the manufacturer’s guidance
  • Failed material removed, not covered up
  • A range of standard colours, depending on the product

See our cost guide or how we’re accredited.

Building owners, agents and FMs in Arborfield

We work for building owners and managing agents on everything from one building to a spread of sites around Arborfield. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Keeping the joints sound

Cleaning and maintenance staff play a part too. Share these points with them:

  • Have the asbestos survey to hand for older buildings
  • Keep bins and bikes away from communal door frames
  • Make mastic part of routine maintenance checks
  • Log resealing dates block by block

Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.

Joints on a building age together so a single failure is a sign to check the rest. Doing them together saves going back again and again.
