How we handle fire rated sealant in Harthill
A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on, one gap at a time. If you have unsealed gaps where pipes and cables go through a wall and open gaps behind door architraves, we can help.
For holiday lets, guest houses and community buildings in or near Harthill, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Each job carries a 12-month guarantee, large or small.

What happens if it’s left?
Fire-rated sealants are less forgiving than ordinary ones. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In a place like Harthill, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why choose Mr Mastic in Harthill

FAQs for Harthill
Do you cover smaller places like Harthill?
Yes, we do. We work across all of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Blackridge station. Can you help?
Yes, landlords and agents are among the people we work for. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How much does fire rated sealant cost in Harthill?
It depends on the job, so we quote each one individually. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.
Do you work in flats, HMOs and commercial buildings?
Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. We agree access and the order of work with you first.
Do you carry out fire risk assessments?
No, we don’t assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings. The product needed can limit the range.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Include fire stopping when you schedule refits
- Make resealing part of every contractor’s brief
- Never patch a fire seal with standard sealant
- Check whether a sealant can be painted before decorating over it
File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It normally takes from a few hours to a few days, depending on the number of gaps and the access. Outdoor work around Harthill depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- Where the tested detail needs backing or fill, we fit it.
- The sealant goes in to the depth its detail sets, then it’s tooled off.
- We record the locations and products used for your records.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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 fails, we can still redo it.
