Mastic sealing in Great Tew, done properly

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on communal entrances and stairwells, communal kitchens and washrooms and balcony and threshold joints, and the usual reasons a site gets in touch are draught complaints from residents or tenants and failed external movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Great Tew, that means joint design, primers and backing rod as standard.

For owners with a single building near Great Tew, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

After the work

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Encourage occupiers to report problems at frames
  • Reduce knocks to communal area joints
  • Group repairs into a planned programme
  • Share the asbestos register when you send details

Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.

One failed perimeter typically means others on the same building are close so a single failure is a sign to check the rest. Doing them together saves going back again and again.

Frames, entrances and external joints in Great Tew

Great Tew sits in one of the drier corners of the country, the South East. 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. At about 65 miles from central London, Great Tew is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.

Property owners at sites such as Enstone Airfield Industrial Estate (to the south of Great Tew) can have mastic renewed between lettings. Older community buildings, Church of St Michael and All Angels among them, often have frames of mixed ages whose mastic varies.

Great Tew is about 8 miles south-west of Banbury, in Oxfordshire. Great Tew sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our Oxfordshire coverage takes in 423 places. There’s a separate page for Oxford, roughly 17 miles from Great Tew.

Anyone looking for mastic sealing in OX7 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Nearby places we also cover include Little Tew (1 mile south-west), Swerford (2 miles north-west), Wigginton (2 miles north), South Newington (3 miles north) and Church Enstone (3 miles south) for mastic joints.

Different surfaces, different methods

Estate-wide resealing programmes

A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.

Why act early in Great Tew

Open external joints let water into walls and around frames. Damp patches, stained plaster and decorating claims can follow and those cost far more to put right. Halls, stores and units around places like Great Tew may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Do you need mastic sealing in Great Tew?

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant, so these repairs rarely last.

If one of these sounds familiar, it’s time for a closer look:

  • Complaints coming in block by block
  • The same joint failures repeated across a portfolio
  • Movement joints with sealant missing
  • Worn sealant at communal door frames

Schools and community buildings such as Great Tew County Primary School need frame and external mastic kept sound like any building.

What your quote should include

  • Will failed sealant be removed rather than covered?
  • Their public liability cover
  • How they handle RAMS and site documents
  • Who will actually carry out the work

How to choose a sealant contractor

On site: what to expect

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking one or more days per building, depending on the joint lengths and the access. If others near Great Tew need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  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. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Getting the site ready

  • Let us know about inductions and permits
  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed

Quotes

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Advice

Quoting for work in Great Tew

These are the things that shape the price:

  • Whether the work must be split into stages
  • Access and working height
  • The size and state of each joint
  • Distance, for remote addresses

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Before you send an enquiry

However big the job, these details speed things up:

  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height
  • The type of building and who uses it
  • Specification clauses that apply

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or use the quote form if you’d rather talk the job through.

Questions we’re asked in Great Tew

Do you take on block-wide or estate-wide mastic work in Great Tew?

Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.

Is Great Tew off your patch?

No. Places such as Great Tew 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.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

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.

Is mastic sealing guaranteed?

There is a 12-month guarantee on our workmanship and we hold public liability insurance.

Can you seal joints high up on a block?

It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
