Doing it in-house
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Floor joint sealing in Downend
Mastic Doctor has worked on joints in commercial buildings for over 20 years. Applicators carry CSCS cards and work to your site rules, and the business is CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. Most enquiries involve a rough ride across broken joints and grimy joint lines spoiling a showroom floor, across saw-cut induced joints, construction joints and joints along racking aisles. A specialist sealant contractor works differently from a general builder: in Downend, that means joint design, primers and backing rod as standard.
Jobs around smaller places like Downend are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. For work around Downend, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- Each area is assessed for joint width, arris damage and the wheels that cross it.
- You get a fixed quote with the product and the phasing set out.
- We remove failed material and packed debris until sound concrete is exposed on both faces.
- Dust is extracted from the joint and primer applied where the manufacturer specifies it.
- The chosen product is placed to its specified depth and trimmed level with the floor.
- The area is handed back once it has cured enough to take traffic.
Preparing the site
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work
- Clear stock, furniture or equipment away from the joints
Get a fixed quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
Why it’s worth doing now in Downend
Open joints are where dirt collects where scrubber-driers can’t get it out. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. Older rural buildings around Downend move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
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 fixed quote and we’ll explain how it’s made up.

When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- Worn screed or surface finishes
- Uneven floors that need grinding or levelling
- Cracks across panels caused by settlement or overload
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

What the job involves on each surface
Retail and showroom floors
Retail work is phased around trading. Give us your opening pattern and access windows and the phasing follows.
Isolation joints at walls and columns
Joints at walls and columns are often missed when floors are sealed and fill up with dirt. We include them in the survey.
When to call us in Downend
An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. At that point it neither holds the edges nor keeps debris out.
Common reasons buildings call us in:
- Sealant pulled out along a truck route
- Grimy joint lines spoiling a showroom floor
- Loading bay joints breaking down
- Filler that has parted from one face
On industrial estates such as Red Shute Hill Industrial Estate, 2.5 miles south-east of Downend, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
What your quote should include
- How the existing material will be dealt with
- What level of public liability insurance do they hold?
- How they’ll work around occupants
- What the guarantee covers, and for how long

Downend: questions and answers
Do you take on work at healthcare sites like West Berkshire Community Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is Red Shute Hill Industrial Estate, near Downend, within your area?
Yes, sites like Red Shute Hill Industrial Estate are within our area, along with the rest of Downend. Photos and a short description are enough for a first look.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you repair broken joint edges?
Filling against broken edges doesn’t last. If the arrises have spalled, we’ll say they need repair before filling, so you can decide how to proceed.
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
How long before trucks can use the joints?
The wait is set by the product’s cure time and cooler floors take longer. We plan the phasing so that waiting time fits your operation.
Floors, slabs and movement joints in Downend
Downend 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. Downend is about 53 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.
In a school such as Chieveley Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Hospital campuses such as West Berkshire Community Hospital, 4.7 miles to the south of Downend, grow in stages, leaving movement joints wherever new blocks meet old.
