Floor joint sealing in Sandridge, done properly
Wet-area floor joints keep water out of the gap behind skirting and plinths. A flexible silicone seal keeps it out. If you have floor edges that trap water and grime and skirting that has pulled away from the floor, we can put it right.
In a village or hamlet like Sandridge, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Floor joint sealing around Sandridge
Floors around Hertfordshire 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.
Schools such as Sandridge School are buildings too, and floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up. Community buildings like St Leonard's Church are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear. If you let a flat or house near St Albans station, a tidy floor and skirting joint helps a rental look ready for the next tenant.

The process
On the day, we look over the joints with you first. We protect the surfaces around the joints before we start. Most jobs take a few hours, depending on the length of joint. Somewhere as small as Sandridge, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- Finally we tool it smooth and explain when the floor can be used and cleaned.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Mention any tricky access

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What affects the cost of floor joint sealing
Every job gets its own quote. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Any mould that needs treating
- The number and length of the joints
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- The address or postcode of the job
- 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, and we will talk you through what we’d do. When it suits you, call 0345 464 0079 or email us.
How the job changes by surface
Skirting boards
Skirting gaps are one of the most common floor joints we seal. The old caulk is removed first so the bead sits on a clean surface.
Wet room and bathroom floors
Bathroom floor edges get wet at every clean. A neat silicone joint keeps it out.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Leave it or put it right?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In a small place like Sandridge, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
