Floor joint sealing in Colthrop, done properly
We have been sealing commercial joints since 2005. Our CSCS-carded applicators follow your site induction and rules, and the business is CHAS accredited and a Constructionline member holding public liability insurance. Finished floor joints in Colthrop carry our 12-month guarantee. We work on forklift and pallet-truck routes, construction joints and joints along racking aisles, and the usual reasons a site gets in touch are grimy joint lines spoiling a showroom floor and sealant pulled out along a truck route. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Colthrop is the same: the right product in a properly prepared joint.
Smaller community and commercial buildings around Colthrop have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
A 12-month guarantee applies to all our work. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we will come back to it.

Do you need floor joint sealing in Colthrop?
Oil, laitance, dust and old cleaning chemicals build up inside joints. Without cutting back to sound, clean concrete the new filler can’t stay bonded.
Clients normally get in touch after noticing one or more of the following:
- Trucks and loads jolting over damaged joints
- Cracked and crumbling joint fill
- Sealant pulled out along a truck route
- Loading bay joints breaking down
At places like Thatcham Business Village, which lies east of Colthrop, joints are sealed a section at a time so operations carry on.

What the job involves on each surface
Flexible floor sealants
Polyurethane floor sealants are available in a range of colours, and we’ll confirm what the specified product offers.
Isolation joints at walls and columns
We plan column and wall joints around racking and fixed plant so nothing has to move unexpectedly.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Colthrop, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- First, the zones and order of work are agreed with you.
- Any joints with broken edges are flagged before work starts.
- Failed material and debris are removed and the joint cleaned.
- The chosen filler or sealant goes in flush with the slab.
- You get a time for each zone to reopen.
Getting the site ready
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Uneven floors that need grinding or levelling
- Spalled arrises, which need an edge repair first
- Structural cracking in the slab

Questions about Colthrop
Is Colthrop too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Would you work within a site like West Berkshire Community Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Why is there a gap next to the joint filler?
Separation normally comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.
Which is better for warehouse joints, filler or sealant?
We decide joint by joint. Where hard wheels cross, a semi-rigid filler is usually right and perimeter or movement joints need flexibility. You’ll see the choice for each area in the quote.
Maintenance after handover
A few simple habits keep the new joints working:
- Clear packed debris from open joints regularly
- Let us know what the floor is cleaned with
- Hold traffic back until the product has cured
- Allow for topping up joints as a new slab settles
A routine walk of the busiest aisles shows how the joints are holding up. Watch for filler pulling away from an edge, fresh chipping or grit collecting and keep photographs so changes are easy to compare.
Grit in an open joint does damage every time a wheel crosses it. Getting it filled stops the damage before it becomes a repair.
