Construction mastic in Kidlington

Site managers want applicators who turn up with the right cards and paperwork. We are a Constructionline member and CHAS accredited, and every applicator holds a CSCS card. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on sanitary and kitchen joints, brick and block movement joints and floor and skirting junctions, and the failures we are asked to look at most are inconsistent sealant finishes from plot to plot and new external sealant already peeling away. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kidlington it comes down to the same thing: the right product in a properly prepared joint.

For a contractor on a smaller site near Kidlington, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What happens if it’s left?

A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Small buildings around Kidlington suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Coloured sealants to suit the setting, where available
  • Colour agreed before work starts
  • Constructionline member for supplier checks
  • Clear, fixed quotes

New build and refits around Kidlington

There are a number of hotels within about 2 miles of Kidlington. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Kidlington is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.

When units on a site such as Cherwell Business Centre, 0.8 miles to the north-west of Kidlington, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors on a campus like University Field Station, 2.9 miles to the south-west of Kidlington, facade and perimeter sealing has to fit around students and term dates.

Kidlington is about 5 miles north-west of Oxford, in Oxfordshire. Any commercial site in Kidlington is covered, for single jobs and planned programmes alike. 423 places across Oxfordshire fall within our area, including Kidlington.

Postcode districts covered here: OX5. Streets here include High Street, Sterling Road and Exeter Road, and sites on any of them can send details for a fixed quote. Kidlington sits on or close to the A4260, useful when we plan access and materials. If your building is just outside Kidlington, we cover Gosford (1 mile south-east), Hampton Poyle (1 mile north-east), Islip (2 miles east), Bletchingdon (2 miles north) and Enslow (3 miles north). A short drive away, we cover Oxford (5 miles south-east), Didcot (15 miles south), Bicester (8 miles north-east), Abingdon-on-Thames (10 miles south), Witney (9 miles west) and Carterton (14 miles west).

Other landmarks nearby include Oxford Castle (4.9 miles south) and Acland Hospital (4.3 miles south). Green spaces nearby include Hook Meadow and The Trap Grounds.

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a site in Kidlington, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. First we take quantities off the drawings and read through the specification.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Areas are sealed plot by plot or floor by floor as the trades hand them over.
  5. Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
  6. We close out snagging and hand over with a 12-month guarantee.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Point out any areas we must not close

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Joints damaged after sign-off by following trades
  • Glazing units that are cracked or misted
  • Oversized gaps that need packing or adjustment by others

If you are not sure, just speak to us on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Cladding and panel joints
  • Internal decorators’ caulk
  • Sanitary and kitchen joints
  • Brick and block movement joints
  • Floor and skirting junctions
  • Window and door perimeters

Common questions from Kidlington clients

Will you plan work around the academic year at somewhere like University Field Station?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is a hospital such as Acland Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Do you take on small jobs?

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

How do you work with the site programme?

We seal plot by plot or floor by floor as areas are released. The sequence is settled with your site team and updated as the programme moves.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

When to call us in Kidlington

Three-sided adhesion is a frequent fault on new work. Bonded to the base of the joint and both sides, sealant can’t stretch evenly.

Look out for the following:

  • Early adhesion failures on new external joints
  • Different trades sealing to different standards
  • Internal caulk splitting as the building dries out
  • Old sealant on a refurbishment that needs stripping before new work

On a healthcare site such as Acland Hospital (4.3 miles south of Kidlington), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Comparing quotes

  • Will failed sealant be removed rather than covered?
  • Their public liability cover
  • Are they CHAS accredited or on Constructionline?
  • How the joint faces will be prepared and primed

Questions to ask before you appoint anyone

Different surfaces, different methods

Kitchens and utility areas

On commercial kitchen fit-outs, hygienic sealants are often specified. Joints are sealed smooth so they’re easy to clean.

Fire-rated sealant where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
