Mastic sealing across Godstow

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

Mastic sealing in Godstow, done properly

Managing agents and housing associations usually need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on communal entrances and stairwells, balcony and threshold joints and external wall and movement joints, and the usual reasons a site gets in touch are communal area joints that look neglected and window mastic that has split and shrunk. For commercial sealant work in Godstow, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Godstow, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Leaks through the frame itself rather than the perimeter
  • Masonry that has broken away beside the joint

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly.

Surfaces we seal

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

For owners and agents in Godstow

Godstow lies roughly 55 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres. Rainfall across the South East, Godstow included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

For a school such as Wolvercote Primary School, perimeter mastic on windows and doors is a holiday job. For owners of several units at places like Jordan Hill Business Park, which lies north-east of Godstow, one programme can deal with frame and external mastic across the lot.

Godstow is about 3 miles south of Kidlington, in Oxfordshire. Commercial clients in Godstow use us for work on mastic joints, as part of our coverage of Oxfordshire. We work across 423 places in Oxfordshire.

Sites close to Godstow are covered too, including Wolvercote (1 mile north-east), Binsey (1 mile south), Sunnymead (1 mile east), Summertown (1 mile east) and North Oxford (1 mile east).

Signs you need mastic sealing in Godstow

The edges of the material itself sometimes break away for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.

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

  • No planned programme for sealant
  • Cracked, hardened mastic round windows on a block
  • The same joint failures repeated across a portfolio
  • Water getting in round frames after rain

Owners of student blocks near University Field Station (to the west of Godstow) can schedule frame and external mastic for the summer vacation.

Before you book anyone

  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
  • Whether their applicators hold CSCS cards

How to choose a sealant contractor

After the work

Regular inspection catches problems early. In particular:

  • Look at the sunniest and most exposed elevations first
  • Keep a record of when each building was resealed
  • Have the asbestos survey to hand for older buildings
  • Make mastic part of routine maintenance checks

Our workmanship is covered for 12 months, so report any failure in that time. Beyond that, routine checks spot the next round of repairs.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

What the job involves on each surface

Commercial and mixed-use buildings

Tenants in commercial buildings need to keep trading so the work is phased.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.

Questions we are asked in Godstow

Do you work for managing agents with blocks near Oxford Parkway station?

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

Is Godstow too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you work for managing agents and housing associations?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

What paperwork can you provide?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

How long does a job like this take?

It depends on the scope, though a typical visit usually takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.

Can you work to our specification?

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

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. If others near Godstow need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  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.

Getting the site ready

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Let us know about inductions and permits

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.
