How we handle expansion joint sealing in Longworth
Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on precast concrete panel joints, cladding panel joints and car park decks and ramps, and what we are called in for most is sealant pulling off the joint face and hardened, cracked sealant on exposed facades. One point of contact handles commercial sealant work in Longworth from the first photos to the final walk-round, whether it’s one building or several.
Jobs around smaller places like Longworth are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Traffic, movement and joints around Longworth
Rainfall across the South East, Longworth included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. Central London is about 59 miles from Longworth. Warehousing clusters around the motorways that ring and radiate from London.
In a school such as Longworth Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. For buildings at a park such as Kingston Business Park, 1.7 miles to the south-east of Longworth, brick and panel movement joints are easy to forget until one leaks.
Longworth is about 7 miles west of Abingdon-on-Thames, in Oxfordshire. We cover commercial sites throughout Longworth, for single jobs and planned programmes alike. Longworth is one of 423 places in Oxfordshire on our list. We also cover Oxford, some 10 miles away.
Work on movement joints is covered throughout OX13, for business premises of every kind. For a building on High Street, Bowbank and Rectory Lane or nearby, send details and we will quote for movement joints. Nearby places we also cover include Hinton Waldrist (1 mile west), Kingston Bagpuize (1 mile south-east), Pusey (3 miles south-west), Charney Bassett (3 miles south) and Lyford (3 miles south). Bigger towns within reach include Oxford (10 miles north-east), Didcot (10 miles south-east), Abingdon-on-Thames (7 miles east), Witney (7 miles north), Carterton (8 miles north-west) and Wantage (7 miles south).

How the job changes by surface
Podium joints
Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.
Car park decks and ramps
Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again.
How a job runs
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. Smaller jobs around Longworth can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000

Your questions answered
Does a site in Longworth have to shut while its joints are sealed?
Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.
Is a smaller place like Longworth outside your area?
Not at all. Longworth is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
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?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What hours do you work?
Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Keep scrapers and ploughs from dragging across joint sealant
- Keep product details with the building records for the next reseal
- Act on the first tear or lifting edge rather than waiting
- Check joints after long freezing spells
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. A routine sweep is the simplest protection.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Crumbling edges that would give a new bead nothing sound to grip
- Cracking or settlement that calls for an engineer’s assessment
- Changing the joint layout or spacing of a structure
If in doubt, phone 01277 525 020 or use the quote form and we will say what we think.
Surfaces we seal

Common problems we fix in Longworth
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Typical triggers for a call:
- Water dripping through deck or ramp joints
- Sealant pulling off the joint face
- Damp inside where a wall movement joint has failed
- New sealant over old, now failing
For estates staff at a university like University of Oxford (1.5 miles north-west of Longworth), building and paving joints are part of the planned maintenance list.
What your quote should include
- Are they CHAS accredited or on Constructionline?
- Who will actually carry out the work
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
