What we do, step by step

Most jobs take a morning or an afternoon for most homes. A visit to Northdown is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

- Old material is removed from the joint.
- Edges are cleaned and dried.
- A flexible sealant suited to the floor is applied.
- Finally, we check the work and talk you through aftercare.

Floor joint sealing for homes and businesses in Northdown
In commercial and industrial units, concrete floor joints take a hammering from wheels and traffic. Each is resealed with a floor-joint product suited to what runs over it. Typical jobs include grout cracking in a straight line across a floor and concrete floor joints that have broken down, on thresholds, commercial floors and concrete floor joints.
In smaller places like Northdown, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
Each job carries a 12-month guarantee, large or small.

What we need to know
When you call or email, these details help:
- The problem you’ve noticed
- Where the property is
- Roughly how big the job is
- A few photos by email, if you can
We quote each job on its own, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Don’t paint over silicone
- Use a well-wrung mop rather than flooding the floor
- Keep caulk for dry, still joints only
- Mark off resealed joints in warehouses
Check the joints after the first winter. Small gaps at the ends can be touched up.
Once concrete joint edges start to break, wheels make it worse. Sealing them early protects the edges and the floor safer.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Large cracks that need a surveyor
- Damaged concrete that needs breaking out and repairing
- Bouncy or failing floorboards
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.

Joints and finishes in Northdown homes
Across Kent, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. That is why the skirting and threshold joints need a flexible seal.
If you look after a church, hall or community building such as St Philip, joints in its floors, skirtings and thresholds need resealing as they wear. For site and facilities teams at buildings such as Palm Bay Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.

Around Northdown

Other landmarks nearby include Westwood Cross (2.1 miles south-west) and Queen Elizabeth the Queen Mother Hospital (1.4 miles south-west).
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why act early in Northdown
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, but the movement soon cracks it. A flexible sealant moves with the floor. In a smaller place like Northdown, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
