Mastic sealing for commercial buildings in Childrey

On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you so you can let residents know what is happening. Entrances and stairwells are kept in use throughout. The enquiries we see most involve mastic failing across several blocks on an estate and worn sealant at communal door frames, across communal entrances and stairwells, communal kitchens and washrooms and external wall and movement joints. Whoever orders the work in Childrey, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For buildings around smaller places like Childrey, we group work so one trip covers it. Photos of each elevation help us quote accurately.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

  • Glazing that needs replacing
  • Frames that are rotten, warped or broken
  • Water coming in from the roof or rainwater goods

Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

What we seal

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

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. If others near Childrey need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  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. Buildings are completed in turn.

Preparing the site

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Avoid piecemeal callouts where you can
  • Include mastic in your cyclical inspections
  • Protect low-level joints in entrances
  • Have the asbestos survey to hand for older buildings

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.

How the quote is worked out

What shapes the price:

  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing
  • Quantities, in metres or numbers

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What we need to price the job

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

  • Any specification or named product
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule
  • How the joints are reached, and at what height

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email a schedule or drawings to discuss it first.

What the job involves on each surface

Communal areas

Joints at low level in communal areas take knocks from bins, bikes and buggies and tend to fail first.

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

For owners and agents in Childrey

At about 60 miles from central London, Childrey 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. Childrey sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

For a school such as The Ridgeway Church of England (C) Primary School, perimeter mastic on windows and doors is a holiday job. Landlords with units on estates such as W&G Industrial Estate, 1.1 miles to the north-east of Childrey, can bring frame, door and external mastic across several units into one programme. Older community buildings, Church of St Mary among them, often have frames of mixed ages whose mastic varies.

Childrey is about 2 miles west of Wantage, in Oxfordshire. Our applicators travel to Childrey for work on mastic joints. Across Oxfordshire, 423 places are covered, Childrey among them. Sites around Oxford have their own page, about 16 miles away.

Your questions answered

Can you quote for mastic across several buildings in and around Childrey?

Yes. Portfolio-wide programmes are a regular request. Send the addresses and photos and we will give a fixed quote.

Is Childrey too small for you to travel to?

No. Places such as Childrey are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Is asbestos a concern with old mastic?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

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 entrances stay in use.

Leave it or put it right?

Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go, under a single quote and a single programme. Around Childrey, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
