Central London is about 52 miles from Harwell. 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.

Office parks like The Core Business Centre (1.3 miles north-west of Harwell) have decks, ramps and clad elevations whose joints take movement every day.

About our floor joint sealing in Harwell
Most industrial slabs are divided into panels by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. We work on construction joints, loading bays and forklift and pallet-truck routes, and the usual reasons a site gets in touch are unfilled floor joints collecting dirt and grit and a rough ride across broken joints. Facilities teams, main contractors and managing agents in Harwell tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Work in a smaller place like Harwell is normally one building at a time, so we gather photographs and measurements first. Getting widths, depths and traffic details up front means one visit, not two.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What else we do in Harwell
Your questions answered
Is Harwell too far out for you?
No. Places such as Harwell are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Would you work within a site like Didcot 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.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How long does a typical visit take?
It depends on the scope, but the work normally takes a day or more, depending on the metres of joint and how many zones the floor is split into. Larger or phased jobs take longer, and we will give you a timescale with the quote.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
What information helps you price floor joint sealing?
Use our quote form, or email photographs and a plan, with the traffic on each area. We then send a fixed quote that shows the products and zones.
Why act early in Harwell
An open joint is a modest filling job while its edges are sound. Left until they break, it needs an edge repair before any filling can start which means more downtime in that zone. Small buildings around Harwell suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Why choose Mastic Doctor in Harwell
- Old sealant cut out, never sealed over
- Workmanship guaranteed for 12 months
- One phone line for London, the South East and Scotland
- Constructionline member for supplier checks

Surface by surface
Saw-cut induced joints
Sawn joints make up most of the joint length in a typical industrial floor. Each one is cleaned out and filled to the specified depth with a flush finish.
Flexible floor sealants
Where joints move more, a flexible polyurethane floor sealant is often used. They don’t hold the arrises up as firmly as a semi-rigid fill, so they suit lighter traffic or movement joints.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Check joint lines on busy aisles regularly
- Keep photographs of joints that look like they’re failing
- Respect the cure time before traffic returns
- Clear packed debris from open joints regularly
Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so the product suits them.
Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.
Work for main contractors and building owners
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Harwell. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
What affects the price in Harwell
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
- How accessible the joints are
- Backing rod, priming and other preparation
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Specification clauses that apply
- Anything awkward about access or site hours
- The site address and postcode
- Whether an asbestos survey exists
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, ring 01277 525 020 or email the details over.
Our process
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. What matters most for a job in Harwell is a clear list of what needs doing, so send photos of each area. A fixed quote follows.
- A floor survey records every joint, its edges and what crosses it.
- You receive a fixed quote showing products and phasing.
- Each joint is cut or routed back to clean, sound concrete.
- We extract the dust and prime the faces if the product needs it.
- Filler or sealant is placed to depth and finished flush.
- We hand each phase back when it can take traffic.
Before we start on site
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
- Move anything stored against the joints
