How we handle expansion joint sealing in Ascott-under-Wychwood
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1, and the bead is tooled so it grips the two faces alone. Most enquiries involve sealant peeling off one face of the joint and car park joints leaking onto vehicles below, on brickwork movement joints, precast concrete panel joints and blockwork control joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Ascott-under-Wychwood it comes down to the same thing: the right product in a properly prepared joint.
For a site near Ascott-under-Wychwood, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.

Advice
Questions we’re asked in Ascott-under-Wychwood
Is Wychwood Business Centre, near Ascott-under-Wychwood, within your area?
Yes. Estates, retail parks and business parks around Ascott-under-Wychwood, Wychwood Business Centre among them, are all within reach. A few photos and the unit address let us price the work.

What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How long will the joint resealing take?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
- Movement on a scale no sealant is meant to absorb
If you’re not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer before you book.

Expansion joint sealing around Ascott-under-Wychwood: how the place shapes the job

Aftercare for building managers
Problems stay small when the joints are checked regularly. In particular:
- Leave barriers in place until fresh joint sealant has cured
- Record the sealant used and the date in the O&M file
- Keep stones and debris out of open joint lines
- Put movement joints on the planned maintenance inspection round
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.
Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
