New build and refits around Bloxham

Bloxham sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 65 miles from Bloxham. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.

Extensions at sites like The Horton General Hospital, 2.9 miles north-east of Bloxham, usually sit beside working departments, and the mastic follows strict access rules. Further education sites such as Oxford and Cherwell Valley College, 3 miles to the north of Bloxham, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Bloxham is about 3 miles south of Banbury, in Oxfordshire. Bloxham sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Oxfordshire, 423 places are covered, including Bloxham. Oxford is covered too, some 19 miles away.

Facade sealing for commercial buildings in Bloxham

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, and we will fit the work around it. If you are dealing with damp patches beside frames after rain and old perimeter mastic that has dried out, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bloxham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

On a small site around Bloxham, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Different surfaces, different methods

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex without tearing.

Precast concrete panels

Concrete edges can be dusty or weak. Faces are cleaned to sound concrete, and damaged edges are reported.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Don’t wait for a second leak before calling
  • Inspect facade joints on a regular cycle
  • Insist on a full cut-out when joints are renewed
  • Check the asbestos register before old mastic is disturbed

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.

Use each reseal to correct the joint: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.

When to call us in Bloxham

New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead, so the new bead peels away within a season or two.

Typical triggers for a call:

  • Old perimeter mastic that has dried out
  • Failed sealant on precast panel joints
  • Perimeter joints where frames meet the structure
  • Air leaks through failed facade joints

New units and refits on sites such as Vantage Business Park (1.2 miles north of Bloxham) need their panel and perimeter joints sealed to the specification.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
  • Can the work be phased to keep areas open?
  • How joint depth will be controlled

Our contractor checklist

FAQs: Bloxham

Is a hospital such as The Horton General Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you cover business parks and estates near Bloxham, such as Vantage Business Park?

Yes, sites like Vantage Business Park are within our area, along with the rest of Bloxham. Send details of the unit and the work through our quote form for a quick quote.

Do we need an asbestos check before resealing?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register. If asbestos is suspected, work stops until it is tested.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How do I request a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.

Honest limits

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

  • Joints whose design needs changing by the specifier
  • Cracked or spalling substrates that need repair before sealing
  • Work on the window or framing system itself

If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Surfaces we seal

  • Stone and brick facade joints
  • Shopfront frames
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Cladding panel joints

From enquiry to sign-off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. What matters most for a job in Bloxham is a clear list of what needs doing. A fixed quote follows.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. Product choice follows the joint’s movement and substrate.
  3. Failed beads are removed in full.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. The finished joints are checked with you.

What we need from you

  • Make sure the joints can be reached
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
