Dollis Hill Floor Joint Sealing
Problem with your floor joints in Dollis Hill? We remove the old material, prepare the joints and seal them properly.
- Perimeter joints in tiled floors filled with grout
- Open gaps along the bottom of skirting boards
- Failed joint filler in concrete floors
Floor joint sealing in Dollis Hill, done properly
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. We work on skirting boards, wet room & bathroom floors and concrete floor joints, and common reasons people get in touch are concrete floor joints that have broken down and cracked grout where a tiled floor needs a movement joint.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How we quote for floor joint sealing
We quote each job individually. This is what makes a difference:
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- When we can work, for business premises
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy
- Access, such as stairs, a lift or height
- The address or postcode of the job
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and give you a clear quote.
Floor joint sealing around Dollis Hill
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Across Greater London, 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.
For site and facilities teams at buildings such as Our Lady of Grace Catholic Junior School, entrance and corridor floor joints take a lot of traffic. If you look after a church, hall or community building such as Church of St Michael, floor and skirting joints in halls and kitchens wear like any others.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Your questions about floor joint sealing in Dollis Hill
Is Dollis Hill in your area for floor joint sealing?
Yes. We work across London and the South East, and Dollis Hill is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Can you help a landlord with a rental near Brent Cross West station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
What causes gaps between the floor and skirting?
It’s normally the floor moving: timber drying in winter, floors settling, or caulk that cannot stretch. A flexible bead keeps up with the movement.
Can grout be replaced with sealant on a tiled floor?
Often, yes. We replace the grout along a suitable line with flexible sealant. If tiles are loose, that needs fixing first.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
Landlord and commercial work in Dollis Hill
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
We work for letting agents and landlords as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

What the job involves on each surface
Wet room and bathroom floors
In a wet room, the floor-to-wall joint is a key line of defence. We reseal it with a flexible silicone suited to wet areas and we will say if the problem looks like more than the joint.
Concrete floor joints
Concrete floors have sawn or formed joints to control cracking. They’re resealed with a product chosen for what runs over them.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for most rooms, longer for large commercial floors for a typical job. In a London area like Dollis Hill, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Old caulk, grout or sealant is removed from the joint.
- The joint is vacuumed clean, with backing fitted wherever depth matters.
- We apply a flexible sealant, or a floor-joint product on concrete, in a suitable colour.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Before we arrive
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on

Advice
What we’re called out for in Dollis Hill
Water and dirt collect in open floor joints. In kitchens and bathrooms, mop water gets into the gap and behind skirting and plinths.
Look out for any of the following:
- Gaps at thresholds between rooms
- Rigid edge joints in tiled floors
- Chipped and open joints in warehouse floors
- Cracked caulk along skirting in bathrooms and kitchens
Dollis Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
What to look for in a quote
- What the cure time is
- How the surfaces are prepared before sealing
- How the colour is chosen
- Whether they seal over old material or remove it
What happens if it’s left?
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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
