What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Intumescent sealants are a type of fire-rated sealant.
Fire rated sealant in Portlethen
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. If you are dealing with fire seals that have cracked with movement and gaps left after a refit or conversion, we can help, whatever the surface.
For holiday lets, guest houses and community buildings in or near Portlethen, the washrooms and kitchens need the same care as any city building, and fire-rated joints should be kept in good order.
Big or small, you get the same one-year guarantee.

Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Portlethen, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes from a few hours to a few days, depending on the number of gaps and the access. Outdoor work around Portlethen depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.

Advice

- Doors that are not fire doors in the first place
- Certifying a building or signing off its fire safety
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think.

What affects the quote in Portlethen
Call for a quick quote. The main things that affect it are:
- How easy the joints are to reach
- Any working-time requirements on site
- The amount of work
- The type of sealant required
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
What to tell us for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
How the job changes by surface
Door frames
Behind most architraves is a gap between frame and wall. We seal any open gap to the product’s tested details so the architrave can be refitted.
Plasterboard walls
Service holes in plasterboard are often rough and oversized. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Include hidden areas like risers in routine checks
- Keep photos of seals that will be hidden
- Keep the record of products and locations with your fire safety documents
- Get damaged fire seals looked at promptly
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.

For seaside hotels, guest houses and holiday lets around Portlethen, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Scotland has its own building regulations, the Building (Scotland) Regulations, with technical handbooks. Fire-rated sealant is installed to the manufacturer’s tested details; we do not certify buildings or carry out fire risk assessments.
