Floor Joint Sealing in Lyndhurst
Professional floor joint sealing in and around Lyndhurst, with old sealant always removed completely.
- Failed seals where bathroom floors meet baths and panels
- Rigid edge joints in tiled floors
- Dirt and water collecting in open floor joints
What happens if it’s left?
Waiting until the next redecoration can mean a winter of draughts and dirt in the gaps. Sealing them now is a short job in most rooms. Around Lyndhurst, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
The cost depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start.

Floor joint sealing in Lyndhurst, done properly
Thresholds are where two floors, or a floor and a door, meet. We seal them with a flexible sealant suited to the floor finishes either side so the joint stays neat. We work on tiled floors, thresholds and skirting boards, and common reasons people get in touch are perimeter joints in tiled floors filled with grout and open gaps along the bottom of skirting boards.
Homes around Lyndhurst range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
Big or small, it’s backed by our one-year guarantee in Lyndhurst and across Hampshire.

What the job involves on each surface
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.
Thresholds
Threshold joints get a lot of feet, so we choose a hard-wearing, flexible product.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most rooms, longer for large commercial floors. For a job in Lyndhurst, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking the floor, the joint and what traffic it takes.
- We remove what’s in the joint now.
- We vacuum out the joint and add backing where the depth needs setting.
- We apply the sealant in a colour that suits the floor.
- The joint is tooled neatly and the cure time explained.
How to prepare
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Mention any leaks or damp you’ve noticed
