Our process

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. If others near Aston Rowant need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Send your site hours and access windows
  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Related advice

Surface by surface

Car park decks and ramps

Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.

Your questions answered

Can you take on a job at a hospital such as Thame Community Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Aston Rowant too far out for you?

No. Places such as Aston Rowant are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Are you fully insured?

Yes. We are fully insured, and the certificate can go with your quote.

What sets the cost

Your fixed quote is built from the real scope. It takes account of:

  • Which sealant the job calls for
  • The size and state of each joint
  • Quantities, in metres or numbers
  • Whether old sealant has to be cut out first

What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote when you’re ready.

What to include in your enquiry

There’s no need for a formal survey. These details are enough to start:

  • Approximate linear metres or a joint schedule
  • Whether the building will be occupied during the work
  • Asbestos survey details if the building is older
  • Clear photos of the problem areas

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to call 01277 525 020 or email the details over.

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. Converted and older buildings near places like Aston Rowant tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

What you get with us

  • Clear, fixed quotes
  • Work carried out by CSCS-carded applicators
  • Old sealant cut out, never sealed over
  • Colours chosen to suit frames, cladding or finishes where possible

Signs you need expansion joint sealing in Aston Rowant

Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks.

It’s worth sending us details if you spot any of the following:

  • Torn sealant in brick or block movement joints
  • Sealant peeling off one face of the joint
  • Damp inside where a wall movement joint has failed
  • Debris jammed in movement joints

Schools like Aston Rowant Church of England Primary School often have long brick elevations with movement joints that age quietly.

Before you book anyone

  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • Their plan for phasing and protecting the area

Our contractor checklist

Expansion joint sealing in Aston Rowant: the local picture

At about 39 miles from central London, Aston Rowant is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Aston Rowant is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints.

Estates like Junction 5 Bates Industrial Estate (2.8 miles south-east of Aston Rowant) combine warehouse slabs, yards and loading bays, all with joints under wheels. For an estate such as Thame Community Hospital (4.3 miles north of Aston Rowant), the joints in ramps, decks and long building elevations all need attention over time.

Aston Rowant is about 4 miles south of Thame, in Oxfordshire. Across the OX49 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. 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.
