Floor joint sealing for homes and businesses in Roxwell
Large tiled floors, and those over underfloor heating, often need movement joints. Where one is needed, we rake out the grout along the right line and replace it with flexible sealant coloured to suit the grout. Typical jobs include caulk that has cracked where the floor moves and open gaps along the bottom of skirting boards, on concrete floor joints, thresholds and commercial floors.
Work in a small place like Roxwell just needs the journey and access planning, and once on site, the job is the same as anywhere.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

How we quote for floor joint sealing
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- Access and height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
Photos help, but a description is a good start. Please mention:
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- If someone has resealed it before

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Why deal with it now?
An open concrete floor joint gets wider every time something heavy crosses it. A sealed joint supports the edges and keeps the damage down. Around Roxwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.

Common questions in Roxwell
Is Roxwell in your area for floor joint sealing?
Yes. We work across London and the South East, and Roxwell is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.
Can you help a landlord with a rental near Chelmsford station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
How long will you be here?
Most jobs take a few hours, depending on the length of joint, including the preparation. We’ll confirm how long when we quote.
Where do you work from?
Mr Mastic is based in Crawley. We cover Roxwell and the rest of Essex.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Can sealant along the skirting be painted?
Where you plan to paint, we do. Silicone in bathrooms and kitchens cannot be painted, so tell us your plans.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the length of joint and we leave things clean and tidy. In a small place like Roxwell, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Preparing for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Ask before painting over a sealed joint
- Sweep along the edges of the floor
- Do not slide heavy items over sealed joints
- Get cracks along tile grout lines looked at early
Silicone sealant isn’t made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
In wet areas, an open floor joint lets water reach the subfloor. Resealing early keeps it out.
Common problems we fix in Roxwell
Concrete floor joints break down when traffic runs over open or failed joints. Hard wheels damage the joint edges until the joint widens.
Signs it’s time to call us include:
- Rigid edge joints in tiled floors
- Open joints that fill with dirt
- Skirting caulk that keeps splitting
- Worn sealant at door thresholds
Letting a property close to Chelmsford station? Then open skirting and floor joints collect dirt and water, so seal them while the property is empty.

New homes and floors in Roxwell
Floors around Essex run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same 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 Church of St Michael and All Angels, floor and skirting joints in halls and kitchens wear like any others.
