Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. Jobs in and around smaller places like Donnington are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000
- Tell us what induction or permit system the site runs

Advice
Expansion joint sealing in Donnington
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Donnington. If you have spalled or broken joint edges in floors and decks and weathered movement joint sealant that no longer flexes, we can help, whatever the surface. For commercial sealant work in Donnington, you deal with one contact from quote to sign-off, whether it’s one building or several.
Around smaller places such as Donnington, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

After the work
A few simple habits keep the new joints working:
- Record the sealant used and the date in the O&M file
- Avoid parking heavy plant or pallets on joint lines
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Put movement joints on the planned maintenance inspection round
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint and we will tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

Common questions from Donnington clients
Do you take on work at healthcare sites like West Berkshire Community Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Donnington off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can you seal car park deck joints?
Yes. These joints take wheels, salt and water, so product choice matters.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

How the job changes by surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces priming where the maker calls for it.
Car park decks and ramps
Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Movement on a scale no sealant is meant to absorb
Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.

For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
What happens if it’s left?
Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. We can split the scope into urgent and planned. Halls, stores and units around places like Donnington may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.
