Common questions in Ashton
Can you help a landlord with a rental near Botley station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Is Ashton within the area you cover?
Yes, Ashton is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Is caulk good enough for skirting?
Caulk works on still, dry joints, but it cracks where there’s movement or water. We use a flexible sealant for most skirting and floor joints.
Can I add another job to the visit?
Yes. Just list everything you need.
What causes gaps between the floor and skirting?
Movement from drying timber and settling floors opens the gap. Rigid fillers split, so we use a flexible sealant.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Floor joint sealing for homes and businesses in Ashton
Good floor joints come down to the right product and clean, prepared edges. We remove what’s there first, the joint is cleaned and backed where needed, then the new sealant goes in. Common call-outs are for floor edges that trap water and grime and caulk that has cracked where the floor moves, across commercial floors, concrete floor joints and tiled floors.
Older homes in small places like Ashton often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

How the job changes by surface
Thresholds
A threshold is where floors and frames meet. A flexible sealant suits both floor finishes.
Tiled floors
Large or heated tiled floors need room to move. Where needed, a line of grout is replaced with flexible sealant.
Joints and finishes in Ashton homes
Across Hampshire, floors range from older suspended timber floors to concrete slabs in newer homes and commercial units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
Letting a property close to Botley station? Then a tidy floor and skirting joint helps a rental look ready for the next tenant. If you look after a building such as Bishops Waltham Infant School, entrance and corridor floor joints take a lot of traffic.

When to call us in Ashton
Grout is rigid, so a tiled floor with nowhere to move cracks along a grout line. You will see a crack running along the grout, showing where a movement joint was needed.
Most people get in touch after spotting one of these:
- Skirting that has pulled away from the floor
- Floor edges that trap water and grime
- Chipped and open joints in warehouse floors
- Open joints around bathroom floor edges
Community buildings like Church of St Peter are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for most rooms, longer for large commercial floors. Somewhere as small as Ashton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we check the joint and the floor and agree which sealant suits it.
- Whatever is in the joint now, whether caulk, grout or sealant, comes out.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- 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
- For indoor joints, keep the area dry beforehand if you can
- For business premises, tell us about site rules or sign-in
- Mention any tricky access

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
How to look after the new joints
Looking after new joints is easy:
- Use furniture pads near skirting
- Act on grout cracks that run in a straight line
- Cone off fresh joints until they’re ready
- Walk round the room once a year and look at the edges
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. Resealing early keeps it out.
What affects the cost of floor joint sealing
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- The old material and how stubborn it is
- The size of the job
- How many areas need sealing
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- Roughly how big the job is
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, phone 0345 464 0079 or send us an email.
Why deal with it now?
Putting new grout into a crack that keeps reappearing doesn’t last. If the floor needs to move there, the grout will crack again. Replacing that line with flexible sealant gives it somewhere to go. Around Ashton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.
