About our expansion joint sealing in Hamstead Marshall
Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors. We work on brickwork movement joints, podiums and floor movement joints and blockwork control joints, and the failures we are asked to look at most are expansion joints filled with dirt and stones and rain penetration at brick or block movement joints. For commercial sealant work in Hamstead Marshall, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places such as Hamstead Marshall, 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.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
From enquiry to sign-off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. Smaller jobs around Hamstead Marshall can be grouped with others nearby. A fixed quote is given before anything starts.
- 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.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Tell us which areas need to stay in use
- Warn occupants and staff about the work
- Explain the parking and delivery arrangements

Your questions answered
Is a hospital such as West Berkshire Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do we have to stop operations in Hamstead Marshall while the joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.
Which product is best for expansion joints?
The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class.
Do you offer coloured sealant?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How long will the joint resealing take?
It typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, with phasing where areas must stay open. We will confirm when each area can be used again.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Signs you need expansion joint sealing in Hamstead Marshall
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 we tell you if the edges need repairing first.
Look out for the following:
- Expansion joints filled with dirt and stones
- Brittle, chalky sealant on external joints
- Sealant peeling off one face of the joint
- Movement joints with split or torn sealant
Large sites such as West Berkshire Community Hospital, 4.8 miles east of Hamstead Marshall, have car parks, service roads and long elevations with movement joints in brick and panels.
What your quote should include
- Their approach to joint depth and backing
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
- Their public liability cover
What sets the cost
To price the job, we consider:
- Whether the work must be split into stages
- Site requirements such as inductions and permits
- Any access equipment needed
- How much existing material needs removing
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Anything awkward about access or site hours
- The postcode of the building
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or email drawings and photos.
