About our mastic sealing in Wytham

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 while we work. We work on communal entrances and stairwells, external wall and movement joints and shopfronts below residential blocks, and the failures we’re asked to look at most are window mastic that has split and shrunk and occupiers reporting cold air round windows. One point of contact handles commercial sealant work in Wytham from the first photographs to the final walk-round, whether it’s one building or several.

Rural conversions near places like Wytham 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

For owners and agents in Wytham

Two care or nursing homes sit less than 2 miles from Wytham. Care home owners need frame and external mastic kept sound without unsettling residents. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.

Student accommodation around universities such as University Field Station, less than half a mile to the north-west of Wytham, is normally managed block by block, which suits a planned mastic programme. Buildings close to stations like Oxford Parkway station (2.4 miles north-east of Wytham) are often flats over shops, with frame mastic to keep sound. Schools and community buildings such as Oxford Academy need frame and external mastic kept sound like any building.

Wytham is about 4 miles north-west of Oxford, in Oxfordshire. We cover Wytham and the rest of Oxfordshire, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 423 places in Oxfordshire, from busy centres to rural villages.

We take on mastic joints across the OX2 postcode area, for business premises of every kind. Close to Wytham, our area also takes in Cassington (2 miles north-west), Botley (2 miles south), Dean Court (2 miles south), Farmoor (2 miles south-west) and Swinford (2 miles west).

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Failed window or door frames, which need a window contractor
  • Asbestos-containing sealant, which we don’t remove
  • Broken glass or failed sealed units

If in doubt, call 01277 525 020 or use the quote form and we will say what we think before you book.

Surfaces we seal

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

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking anything from a day to a few weeks, depending on the number of buildings and joints. For work around Wytham, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Getting the site ready

  • Let building users know which areas are affected
  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints

Ask for a quote

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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 easy to get wrong without experience.

Why deal with it now?

Adding sealant to cyclical maintenance is an easy win. Waiting until leaks appear means working under pressure with less control over timing. Halls, stores and units around places like Wytham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

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

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • Work to your specification and the manufacturer’s guidance
  • Colours confirmed for the specified product
  • A Constructionline member, so easy to vet

Questions we’re asked in Wytham

Do you work in occupied care homes around Wytham?

Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we’ll work to them.

Is Wytham too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

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.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Quoting for work in Wytham

A fixed quote reflects the actual work. It takes account of:

  • Whether the work must be split into stages
  • Which sealant the job calls for
  • Distance, for remote addresses
  • Removal of failed or old sealant

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 quote when you’re ready.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • Where the site is, with the postcode
  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • Any dates the work must fit around

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

After the work

A few simple habits keep the new joints working:

  • Start inspections with the most exposed faces
  • Share your contractor requirements early
  • Have the asbestos survey to hand for older buildings
  • Check sealant joints during planned building inspections

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

Mastic fails gradually, then all at once in a wet spell. Resealing when cracking first shows avoids water damage and the complaints that come with it.
