Mastic sealing near Ascott d'Oyley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Ascott d'Oyley may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  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.

What we need from you

  • Warn occupants and staff about the work
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Mastic sealing in Ascott d'Oyley

For blocks and buildings in Ascott d'Oyley and across Oxfordshire, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photographs of typical joints and a rough idea of quantities let us give a quick quote, and site visits can be arranged. We work on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints, and the failures we are asked to look at most are open joints in brickwork or panels and worn sealant at communal door frames. For commercial sealant work in Ascott d'Oyley, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

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

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Planned mastic for Ascott d'Oyley portfolios

The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Ascott d'Oyley is about 68 miles from central London. Managed blocks of flats are a big part of commuter-belt property.

Churches, halls and community buildings such as Church of the Holy Trinity are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. With historic buildings such as Minster Lovell Hall (to the south of Ascott d'Oyley) in the wider area, owners of older properties around Ascott d'Oyley should expect mastic to need a product that suits old masonry.

Ascott d'Oyley is about 6 miles north-west of Witney, in Oxfordshire. We send applicators to Ascott d'Oyley for mastic joints, handled exactly as we handle every other area. Our Oxfordshire coverage takes in 423 places, large and small. Oxford is covered too, around 16 miles from Ascott d'Oyley.

What we’re called out for in Ascott d'Oyley

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

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

  • Worn sealant at communal door frames
  • Brittle perimeter mastic across a building
  • Draughts at frames across a block
  • Estate-wide sealant that is simply worn out

For owners of several units at places like Wychwood Business Centre, 1.8 miles to the west of Ascott d'Oyley, one programme can deal with frame and external mastic across the lot.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • What level of public liability insurance do they hold?
  • Whether their applicators hold CSCS cards
  • Their plan for phasing and protecting the area

How to choose a sealant contractor

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Cost factors for mastic joints

These are the things that shape the price:

  • Backing rod, priming and other preparation
  • Location, for remote and island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • The product your specification calls for
  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Asbestos survey details if the building is older

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

What we can’t put right

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Broken glass or failed sealed units

If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.

What we seal

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

Questions about Ascott d'Oyley

Can you quote for a block close to Ascott-Under-Wychwood station?

Yes. Blocks of any size are within what we do. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.

Do you cover business parks and estates near Ascott d'Oyley, such as Wychwood Business Centre?

Yes. We cover Ascott d'Oyley and the area around it, including industrial estates, business parks and retail parks such as Wychwood Business Centre. Photos and a short description are enough for a first look.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Is asbestos a concern with old mastic?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
