Need expansion joint sealing in Fleet Marston?
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Leave it or put it right?
Resealing is usually the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. Around Fleet Marston, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why appoint us
- CSCS-carded applicators
- One contact handling all your sites
- Coloured sealants to suit the setting, where available
- Specification-led, product-correct work

Expansion joint sealing for commercial buildings in Fleet Marston
Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. We work on cladding panel joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are movement joints with split or torn sealant and water getting into the wall through a failed joint.

Smaller community and commercial buildings around Fleet Marston have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

What else we do in Fleet Marston

Where floor joints take the most wear near Fleet Marston
Rainfall across the South East, Fleet Marston included, is lower than in many parts of the UK. 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. Fleet Marston is about 40 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.
If you manage units on an estate such as Bicester Road Industrial Estate (1.3 miles south-east of Fleet Marston), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Another example is Broadfields Retail Park, 1.5 miles south-east of Fleet Marston, where floors and yards would be done in stages around the occupiers.
Fleet Marston is about 2 miles north-west of Aylesbury, in Buckinghamshire.

What affects the price in Fleet Marston
Your fixed quote is built from the real scope. It allows for:
- Backing rod, priming and other preparation
- Removal of failed or old sealant
- Distance, for remote addresses
- The site’s rules and procedures
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.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Access details, including height
- Clear photos of the problem areas
- Specification clauses that apply
- The site address and postcode
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Fleet Marston need work, visits can be combined. A fixed quote is given before anything starts.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- Point out parking and an unloading spot
- For older buildings, check the asbestos register before work

Advice
Your questions answered
Can you take on a job at a hospital such as Royal Buckinghamshire Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Can you work at a site such as Bicester Road Industrial Estate, by Fleet Marston?
Yes. Our area takes in Fleet Marston and its surroundings, with estates and business parks such as Bicester Road Industrial Estate included. A few photos and the unit address let us price the work.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
What the job involves on each surface
Brickwork and blockwork joints
Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it, then seal and tool the joint.
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.
Signs you need expansion joint sealing in Fleet Marston
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.
Clients typically get in touch after noticing something like this:
- Spalled or broken joint edges in floors and decks
- Car park joints leaking onto vehicles below
- Joints where the bead has lost adhesion
- Weathered movement joint sealant that no longer flexes
Hospital campuses such as Royal Buckinghamshire Hospital (2.3 miles east of Fleet Marston) grow in stages, leaving movement joints wherever new blocks meet old.
Questions to ask before you book
- What level of public liability insurance do they hold?
- Are they CHAS accredited or on Constructionline?
- How the existing material will be dealt with
- How joint depth will be controlled
