Floor joint sealing in Thedden
Floor joint sealing is mostly about choosing the right product and preparing the joint. Old caulk, grout or failed sealant comes out first, the joint is cleaned and backed where needed, then the new sealant goes in. If you are dealing with cracked caulk along skirting in bathrooms and kitchens and chipped and open joints in warehouse floors, we can put it right, on wet room & bathroom floors, tiled floors and skirting boards alike.
For a small place like Thedden, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
There’s a 12-month guarantee on every job, large or small.

Floor joint sealing in Thedden: local notes
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. That’s why the skirting and threshold joints need a flexible seal.
If you look after a building such as Amery Hill School, floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. For landlords with property near Alton station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.

Why deal with it now?
Putting new grout into a crack that keeps reappearing does not last. If the floor needs to move there, the grout will crack again. A flexible movement joint is the fix. Around Thedden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Other services in Thedden
Do you need floor joint sealing in Thedden?
Timber floors and skirting shrink and swell through the year. In winter, with the heating on, timber dries and gaps open, then close again in damper months.
The problems people usually mention when they call are:
- Cracked grout where a tiled floor needs a movement joint
- Grout used at the floor edge instead of sealant
- Skirting that has pulled away from the floor
- Failed joint filler in concrete floors
Community buildings like St Peter's are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.
What your quote should include
- Who does the work, and how experienced they are

We will not take on work that won’t last, so these are the limits:

- Water getting under the tiles from elsewhere

Do you have insurance?
Yes. We’re fully insured.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you seal kitchen plinths to the floor?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone in a colour to suit.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep caulk for dry, still joints only
- Have a cracking tiled floor checked before tiles break
- Check skirting joints after the heating season
- Keep heavy wheels off new concrete joints until cured
Avoid flooding the floor when you clean. 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.
How we quote for floor joint sealing
Call for a quick quote. What matters most is:
- When we can work, for business premises
- The number and length of the joints
- Whether there’s mould to deal with
- Access and height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Where the property is
- Pictures of the joints, sent by email
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, phone 0345 464 0079 or email us.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning or an afternoon for most homes. Somewhere as small as Thedden, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the gap and the floor type and agree the right sealant.
- 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.
- The sealant goes in, chosen for the floor and coloured to suit it.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises

Different surfaces, different methods
Tiled floors
Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines.
Thresholds
Thresholds between rooms meet two floors and often a door frame. A flexible sealant suits both floor finishes.
