Shephall: your questions answered
Do you work for landlords with property near Stevenage station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you cover smaller places like Shephall?
Yes. Shephall is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Shephall and the rest of Hertfordshire, along with the rest of our area.
Do you seal warehouse floor joints?
Yes. Old filler is cleaned out and the joint resealed with a floor-joint product. Let us know about the traffic.
Do you seal kitchen plinths to the floor?
Yes. We cut out any old sealant or caulk and reseal with flexible silicone, colour-matched where it shows.
What do you need from me for a quote?
A short description and the location, plus photos if you have them. We will ask anything else we need to know.
Can you add a movement joint to a tiled floor?
Often, yes. Straight cracks in grout often show where a movement joint was needed. We rake out that line and seal it with flexible sealant.
Floor joint sealing for homes and businesses in Shephall
Tiled floors can crack along the grout when there’s no room for movement. We can turn a line of grout into a movement joint by replacing it with flexible sealant. If you are dealing with gaps at thresholds between rooms and floor edges that trap water and grime, we can put it right, whatever the surface.
In smaller places like Shephall, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Shephall
How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most rooms, longer for large commercial floors for a typical job. For a job in Shephall, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the gap and the floor type and agree the right sealant.
- We take out any old caulk, sealant or grout along the line.
- 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.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
Getting ready for the visit
- Clear items away from the joints we’re working on
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Advice
What the job involves on each surface
Skirting boards
Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking painted or coloured to match.
Tiled floors
Perimeter joints in tiled floors should be sealant, not grout. We rake out any grout there and reseal.
Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Act on grout cracks that run in a straight line
- Keep dirt out of the joints
- Cone off fresh joints until they’re ready
- Use a well-wrung mop rather than flooding the floor
Mop with a well-wrung mop rather than flooding the floor. Less water at the edges helps the joints last.
Sealing a gap while it’s small is a quick job. Ignored, they fill with dirt and open further over time.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Why deal with it now?
Open joints along wet floors let water into the subfloor and behind skirting. Sealing them now keeps the problem at the surface. In an older home around Shephall, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Joints and finishes in Shephall homes
Shephall is part of Stevenage, one of the post-war new towns. Newer neighbourhoods have been added to Stevenage over the years. Newer homes need snagging; older ones need their joints renewing. Floors around Hertfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
If you look after a church, hall or community building such as Church of Saint Mary, floor and skirting joints in halls and kitchens wear like any others. If you let a flat or house near Stevenage station, gaps at skirtings and thresholds are worth sealing between tenancies. For site and facilities teams at buildings such as Peartree Spring Primary School, floor and threshold joints in busy corridors wear quickly and are best resealed early.
