Expansion joint sealing across Oxfordshire: what to expect

For movement joints in Oxfordshire, photos and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. To discuss the joints first, phone 01277 525 020 or email the details over. We work on car park decks and ramps, cladding panel joints and brickwork movement joints, and the usual reasons a site gets in touch are hardened, cracked sealant on exposed facades and debris jammed in movement joints.

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish.

The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
You get a fixed quote with the product and its movement capability stated.
Old sealant and filler are cut out and the joint faces cleaned back to sound material.
Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
Each joint is inspected and handed over with our 12-month guarantee.

What affects the price in Oxfordshire

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Floors, slabs and movement joints across Oxfordshire

Most floor and movement joint work across Oxfordshire has to happen while sites keep operating, so we phase it bay by bay, aisle by aisle or deck by deck.

All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, and every job in Oxfordshire starts with access, parking and site rules.

Oxford: For an estate such as Warneford Hospital (under half a mile east of Oxford), the joints in ramps, decks and long building elevations all need attention over time. A campus such as Oxford Brookes University Headington Campus, less than half a mile north-east of Oxford, has long runs of movement joint in its buildings, decks and paving.

Cost factors for movement joints

To price the job, we consider:

Location, for remote and island sites
How much there is to seal
Specialist products, such as fire-rated or hygienic sealants
Working within restricted access windows

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

Access details, including height
Rough lengths or quantities, or drawings if you have them
The postcode of the building
Any specification or named product

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

Site staff or a sealant specialist?

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Different surfaces, different methods

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down.

Comparing quotes

The named product and why it was chosen
How joint depth will be controlled
Will failed sealant be removed rather than covered?
What site paperwork they can supply

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:

Proprietary pre-formed expansion joint systems
Concrete or masonry repairs along the arrises
A joint that has to be widened or re-detailed before it can work

Questions about Oxfordshire

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

How long does movement joint sealing take?

It typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access and phased work can stretch that to suit your site. Cure time before reopening is confirmed on the day.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

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, since fresh sealant will not bond reliably to aged material.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Can you work while the building is occupied?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
