Floor joint sealing for homes and businesses in Lasswade
Gaps along the bottom of skirting are common in new and older homes alike. Decorators’ caulk normally cracks where there’s movement, so we use a flexible sealant that moves with the floor. We work on tiled floors, concrete floor joints and wet room & bathroom floors, and people most often call us about gaps at thresholds between rooms and grout used at the floor edge instead of sealant.
For a place like Lasswade, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Whatever the size of the job, it’s backed by our one-year guarantee.

Floor joint sealing in Lasswade: local notes
Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up. Across Midlothian, 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.
Managing a site like Lasswade High School Centre? Then floor joints in corridors, halls and entrances take heavy wear and need resealing before the edges break up.

Common problems we fix in Lasswade
Decorators’ caulk is often used along skirting because it’s cheap and paintable. It cracks where there’s movement or water so the gap reappears.
Any of these means the joints need attention:
- Caulk that has cracked where the floor moves
- Skirting that has pulled away from the floor
- Floor edges that trap water and grime
- Rigid edge joints in tiled floors
If you let a flat or house near Eskbank station, open skirting and floor joints collect dirt and water, so seal them while the property is empty.
Before booking anyone
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- How long the guarantee is
How it works
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most rooms, longer for large commercial floors. Outside jobs in Lasswade need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We clear the edges of the floor so the joints are easy to reach.
- We take out the cracked caulk, grout or old sealant.
- Edges are cleaned and dried.
- We apply a flexible sealant suited to the floor and smooth it.
- Finally, we check the work and talk you through aftercare.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive

Where are you based?

Can you match the sealant colour?
We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
What do you need from me for a quote?
A short description and the location. If we need more, we’ll ask.
Can grout be replaced with sealant on a tiled floor?
Often, yes, at the edges and along suitable lines. The grout is raked out and replaced with a flexible sealant in a colour to suit.
Is there a guarantee?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Different surfaces, different methods
Tiled floors
Tiled floors need movement joints at edges and across large areas. We replace grout with flexible sealant along the right lines.
Skirting boards
Gaps between skirting and floor open as timber and floors move. A flexible sealant closes the gap without cracking.

What affects the quote in Lasswade
For a quick quote, just ask. What matters most is:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The amount of work
- How many areas need sealing
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- Photos by email, if that is easy
- Whether it has been sealed before
- How many joints, rooms or windows are involved
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, email us at info@mrmastic.co.uk.
Why deal with it now?
The right product depends on the floor and the traffic: flexible sealant for skirting and tiles, silicone in wet areas, and floor-joint products for concrete. Using the wrong one is why many floor joints fail. Around Lasswade, water from a failed joint in an older stone home can soak into timber and plaster.
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. Your quote takes all of that into account.
Why book with us
- We never seal over old sealant
- Colour agreed with you before work begins
- 4.9 on Google from 180+ five-star reviews
- White, clear, grey or coloured to suit, where the product allows

When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Tiles that have lifted or broken
- Cracked or broken concrete slabs
- Bouncy or failing floorboards
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Surfaces we seal
- Commercial floors
- Skirting boards
- Wet room & bathroom floors
- Concrete floor joints
- Tiled floors
- Thresholds
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Avoid caulk in bathrooms and kitchens
- Walk round the room once a year and look at the edges
- Do not slide heavy items over sealed joints
- Cone off fresh joints until they’re ready
Have a look at the joints once the heating season is over. Small gaps at the ends can be touched up early on.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
