Why it’s worth doing now in Hartwell
Patching the worst lengths of a joint can make sense short term. The remaining sealant is often close to failing too, and a second visit means paying for access again. Where it helps, we quote both options. For buildings around smaller places like Hartwell, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Expansion joint sealing for commercial buildings in Hartwell
We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on car park decks and ramps, blockwork control joints and podiums and floor movement joints, and what we’re called in for most is joints where the bead has lost adhesion and chipped joint edges on forklift routes. Whether you call it commercial sealant work, mastic application or joint sealing, in Hartwell it comes down to the same thing: the right product in a properly prepared joint.
Around smaller places such as Hartwell, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When to bring in 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. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What sets the cost
Quotes vary with the job. Expect it to depend on:
- Joint width, depth and condition
- The site’s rules and procedures
- Whether the work must be split into stages
- The product specified
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Send us:
- Whether an asbestos survey exists
- Whether the building will be occupied during the work
- Approximate linear metres or a joint schedule
- Clear photos of the problem areas
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Your questions answered
Is a smaller place like Hartwell outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you cover business parks and estates near Hartwell, such as Bicester Road Industrial Estate?
Yes. Estates, retail parks and business parks around Hartwell, Bicester Road Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Can a joint be sealed if the edges are broken?
Spalled edges need repairing before a new seal will last, and we will point out where that’s the case. A bead on a broken edge soon lets go.
What timescale should we allow for resealing expansion joints?
It typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote, including any phasing.
Can you work on car park ramps and decks?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Honest limits
Being straight saves everyone time. Fresh joints won’t solve:
- Joints too narrow for the movement, which need redesigning by the engineer
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Proprietary pre-formed expansion joint systems

- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
