Expansion joint sealing in Hethe: the local picture
Hethe is about 55 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Rainfall across the South East, Hethe included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.
Sites like Bicester Community Hospital (to the south of Hethe) carry ambulances, deliveries and visitors’ cars over their road and deck joints. Schools such as Fringford Church of England Primary School have movement joints in their walls and floors that are easy to overlook. For an occupier at a site such as Baynards Green Trading Estate, 2.8 miles to the west of Hethe, the joints at loading doors and dock levellers typically see the hardest wear.

Expansion joint sealing in Hethe
A movement joint only works while its seal does. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. The enquiries we see most involve expansion joints split through the centre of the bead and leaks through car park deck joints onto the level below, on cladding panel joints, brickwork movement joints and precast concrete panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hethe it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Smaller community and commercial buildings around Hethe have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Our workmanship is guaranteed for 12 months, in Hethe as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Leaks coming from the membrane rather than the joint seal
- Cracking or settlement that calls for an engineer’s assessment
- Changing the joint layout or spacing of a structure

What we seal
- Precast concrete panel joints
- Blockwork control joints
- Brickwork movement joints
- Cladding panel joints
- Car park decks and ramps
- Podiums and floor movement joints
After the work
Keep the joints in good shape with a few simple steps:
- Clear dirt from joint lines during routine cleaning
- Keep scrapers and ploughs from dragging across joint sealant
- Reopen bays and walkways only after the stated cure time
- Plan racking layouts so feet don’t land on a joint
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file, so the next reseal starts with the facts.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
What happens if it’s left?
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. We cut out the old seal and prepare the faces every time. One visit to deal with every failing joint makes more sense than several trips to a place like Hethe. Send photographs of each area and we’ll quote for the lot.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Our process
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Smaller jobs around Hethe can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work 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.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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.
Preparing the site
- Send your site hours and access windows
- Tell staff and tenants when we’ll be in
- Send asbestos survey details if the building is pre-2000

What else we do in Hethe
Doing it in-house
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.
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. For that reason, many FMs and contractors use a sealant specialist from the outset.
FAQs: Hethe
Can you work on a hospital site such as Bicester Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work at a site such as Baynards Green Trading Estate, by Hethe?
Yes. Our area takes in Hethe and its surroundings, with estates and business parks such as Baynards Green Trading Estate included. Photos and a short description are enough for a first look.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane, and the specification has the final say.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What sets the cost
Quotes vary with the job. It mainly depends on:
- The total length or number of joints
- Induction, permit and paperwork requirements
- Which sealant the job calls for
- Travel to remote or island sites
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- A wide shot and a close-up of the area
- Where the site is, with the postcode
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or email a schedule or drawings.
