Floor Joint Sealing in Heathrow
Sealing skirting-to-floor joints, tiled floor movement joints and concrete floor joints for householders, landlords and businesses in Heathrow. Fully insured, ARBOMaster approved and guaranteed for a year.
- Gaps at thresholds between rooms
- Skirting caulk that keeps splitting
- Gaps opening between the floor and skirting
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Floor joint sealing in Heathrow, done properly
Thresholds are where two floors, or a floor and a door, meet. We use a flexible product that suits both floors in a colour to suit. We work on concrete floor joints, skirting boards and wet room & bathroom floors, and people most often call us about failed seals where bathroom floors meet baths and panels and chipped and open joints in warehouse floors.
Around Heathrow, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Your job is guaranteed for a year, as with all our work.

Heathrow questions
Is Heathrow in your area for floor joint sealing?
Yes, Heathrow is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you work for landlords with property near Heathrow Terminals 2 & 3 Rail station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Will I be able to paint over the new joint?
For painted skirting, we use a flexible product that can be painted. Silicone is not made to be painted, so it’s kept for wet areas and unpainted joints.
Do you guarantee your work?
Yes. All our work carries our 12-month guarantee.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
How long will you be here?
As a guide, most jobs take a few hours for most rooms, longer for large commercial floors. Larger jobs naturally take longer, and we will say how long yours will take.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Why act early in Heathrow
Dirt builds up in open joints, and they look untidy. A neat sealed joint is easier to clean and look tidier. In a small place like Heathrow, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

When to call us in Heathrow
Concrete floor joints break down when traffic runs over open or failed joints. Pallet trucks and trolleys knock the edges away.
Keep an eye out for these signs:
- Skirting caulk that keeps splitting
- Failed seals where bathroom floors meet baths and panels
- Open gaps along the bottom of skirting boards
- Cracked grout where a tiled floor needs a movement joint
Managing a site like Bedfont Primary School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.
Questions to ask before booking
- How the surfaces are prepared before sealing
- Who turns up on the day
- What product goes in the joint
- What happens if they find a problem under the old sealant
What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Floors that are uneven or need levelling
- Concrete repairs beyond the joint
- Movement too big for a sealant joint
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before booking.

Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.
