Expansion joint sealing for commercial buildings in Sunningwell
The seal is what lets a movement joint do its job. 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 joints packed with grit and debris and spalled or broken joint edges in floors and decks, across car park decks and ramps, precast concrete panel joints and blockwork control joints. Facilities teams, main contractors and managing agents in Sunningwell tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller community and commercial buildings around Sunningwell have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Looking after the joints
After handover, a little attention goes a long way:
- Avoid parking heavy plant or pallets on joint lines
- Clear dirt from joint lines during routine cleaning
- Keep product details with the building records for the next reseal
- Report split or peeling joint sealant early
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.
A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.
How the job changes by surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed, and we’ll tell you if any edges need repairing first.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.
Do you need expansion joint sealing in Sunningwell?
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. A sealant that isn’t trafficable won’t last there.
Any of the following is a good reason to get the joints checked over:
- Hardened, cracked sealant on exposed facades
- Previous reseals laid over old sealant
- Car park joints leaking onto vehicles below
- Joints where the bead has lost adhesion
Parks like Wootton Business Park, 1.6 miles to the west of Sunningwell, combine paved areas, car parks and building elevations, each with joints that move.
Before you book anyone
- What the guarantee covers, and for how long
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
- Is the sealant right for the movement and the substrate?
General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions about Sunningwell
Is Sunningwell too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does your area include sites such as Wootton Business Park, near Sunningwell?
Yes. We cover Sunningwell and the area around it, including industrial estates, business parks and retail parks such as Wootton Business Park. Send details of the unit and the work through our quote form for a quick quote.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Can staff carry on working while you are here?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Does weather matter for sealant work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Is movement joint sealing guaranteed?
It’s backed by our 12-month guarantee. Tell us right away if a joint we sealed gives trouble in that time.
How a job runs
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Rural sites near Sunningwell may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.

What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- A joint that has to be widened or re-detailed before it can work
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly.

Joints that move: notes for Sunningwell
Sunningwell sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint. Sunningwell is about 53 miles from central London. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
Retail centres such as Fairacres Retail Park, 2.3 miles to the south of Sunningwell, have floors, service yards and car parks with joints under constant traffic. Phasing is what makes joint work possible on busy sites such as Radley Road Industrial Estate (1.7 miles south-east of Sunningwell): one bay, aisle or car park row at a time.
