Expansion joint sealing in Aston

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

From enquiry to sign-off

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. If others near Aston need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Let us know about inductions and permits

Get a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email the details over.

Advice

About our expansion joint sealing in Aston

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. If the arrises are already broken, we will say so before sealing, and phased work keeps areas in use. Site teams most often ask us about weathered movement joint sealant that no longer flexes and spalled or broken joint edges in floors and decks, across podiums and floor movement joints, cladding panel joints and blockwork control joints. One point of contact handles commercial sealant work in Aston from the first photos to the final walk-round, for single jobs and planned programmes alike.

For a site near Aston, measurements and photographs up front mean one trip where possible. Note joint widths and the traffic that uses them, and we’ll take it from there.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • Phasing around occupants
  • Travel to remote or island sites
  • Joint width, depth and condition
  • Quantities, in metres or numbers

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • When you need the work done

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

Floors, slabs and movement joints in Aston

Aston is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. The 3 miles around Aston take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Parks like Bampton Business Centre North (to the south-west of Aston) combine paved areas, car parks and building elevations, each with joints that move. Phasing is what makes joint work possible on busy sites such as Bampton Business Centre (South) (2.4 miles south-west of Aston): one bay, aisle or car park row at a time.

Aston is about 4 miles south of Witney, in Oxfordshire. Anywhere in OX18, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Aston is one of 423 places we cover in Oxfordshire. For work in that direction, see our Oxford page, about 12 miles away.

Commercial sites across OX18 are covered for movement joints. We cover commercial and managed buildings on Cote Road, Saxel Close and Woodbridge Close and the roads nearby. If your building is just outside Aston, we cover Bampton (2 miles west), Weald (2 miles west), Curbridge (3 miles north), Black Bourton (4 miles west) and Clanfield (4 miles west). Further afield, our area takes in Oxford (12 miles east), Didcot (14 miles south-east), Abingdon-on-Thames (10 miles east), Witney (4 miles north), Carterton (5 miles north-west) and Wantage (10 miles south).

Landmarks near Aston

A little further out are Longworth Hospital (5.7 miles south-west) and Bampton Castle (2.1 miles west).

Aston: questions and answers

Is Aston too small for you to travel to?

No. Places such as Aston are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Longworth Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Common problems we fix in Aston

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

These are often picked up first by site or facilities staff:

  • Joints where the bead has lost adhesion
  • Water getting into the wall through a failed joint
  • Hardened, cracked sealant on exposed facades
  • Layers of sealant in a movement joint

For estates staff at a university like University of Oxford (2.3 miles south-east of Aston), building and paving joints are part of the planned maintenance list.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?
  • Who will actually carry out the work
  • How they’ll work around occupants

How to choose a sealant contractor

Why it’s worth doing now in Aston

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we’ll say so before quoting. Converted and older buildings near places like Aston tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Why choose Mastic Doctor in Aston

  • A range of standard colours, depending on the product
  • Public liability insurance in place
  • Constructionline member for supplier checks
  • Health and safety: CHAS accredited

Commercial clients in Aston

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Aston can sit alongside others in a wider programme.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
