Floor joint sealing for commercial buildings in Amersham
We work on warehouse aisles, dock areas, factory floors, retail units and showrooms. Each job is priced from the metres of joint, their condition and the access windows we get and the figure is fixed before work begins. Most enquiries involve trucks and loads jolting over damaged joints and soft sealant dragged out of trafficked joints, on joints along racking aisles, loading bays and construction joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Amersham, preparation and product choice get the time they need.
Towns such as Amersham usually have an industrial estate or a few business units, with warehouse floors and loading areas. Small units are often busy, so joints are done at times that suit the occupier.
A 12-month guarantee applies to all our work in Buckinghamshire. If an installation problem shows up, ring 01277 525 020 or use the quote form and we will arrange a return visit.

Surface by surface
Retail and showroom floors
Shop and showroom floors often have exposed slab joints, especially with polished or coated concrete. A flush, neat fill in a suitable colour keeps the floor looking right and confirm which colours the product comes in.
Saw-cut induced joints
Saw cuts are made soon after the slab is cast so shrinkage cracks follow a line. They are narrow but open up as the panels shrink, and on truck routes they need a filler that supports the edges.
What affects the price in Amersham
Quotes vary with the job. It mainly depends on:
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- Induction, permit and paperwork requirements
Small jobs and large programmes are priced from the same things: 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.
Details that help us quote
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- The type of building and who uses it
- Where the site is, with the postcode
- How the joints are reached, and at what height
- When you need the work done
Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. For a chat about it beforehand, give us a call on 01277 525 020 or send photos by email.
Looking after the joints
For the best life from the joints:
- Put loading bays at the top of the list
- Sweep debris out of open joints until they can be filled
- Respect the cure time before traffic returns
- Ask drivers not to drag forks or pallets
Ask drivers not to drag forks or pallets along the floor. Even a well-filled joint can be damaged by steel scraping along it.
Grit in an open joint does damage every time a wheel crosses it. Filling it ends that cycle before it becomes a repair.
How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need, and our waste is bagged and taken away as we go. In a town such as Amersham, most jobs are single buildings. We start with your photos, drawings or a site visit, then send a fixed quote.
- First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
- A fixed quote follows, listing the treatment for each area and the order of work.
- Old filler, debris and contamination are cut or routed out back to clean concrete.
- We vacuum each run and prime it if the chosen product requires a primer.
- We fill each joint to depth and finish it flush so wheels roll straight across.
- We tell you when each zone can carry trucks again and move on to the next.
Getting the site ready
- Point out any areas we must not close
- Tell staff and tenants when we will be in
- Tell us your opening times and when work is allowed

Related advice
What happens if it’s left?
Painting or coating straight over joints rarely lasts. Joints need their own treatment before or alongside any coating work. For businesses and landlords in Amersham, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.
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.

Questions we are asked in Amersham
Will you take on work at estates like Corinium Industrial Estate, close to Amersham?
Yes, sites like Corinium Industrial Estate are within our area, along with the rest of Amersham. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
Would you work within a site like Amersham Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Why has the filler pulled away from one side?
On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.
Floor joint sealing around Amersham: what changes locally
At least three named trading, business or retail sites lie within about 3 miles of Amersham. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. At about 25 miles from central London, Amersham is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
Another example is St. Georges Industrial Estate, 0.7 miles south-east of Amersham, where floors and yards would be done in stages around the occupiers. If you manage units on an estate such as Corinium Industrial Estate, which lies east of Amersham, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. Large sites such as Amersham Hospital (1.3 miles south-west of Amersham) have car parks, service roads and long elevations with movement joints in brick and panels.
