Fire rated sealant in Tyttenhanger
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on pipe & cable gaps, linear gaps and plasterboard & masonry, and people most often call us about open joints along the top of partitions and ordinary sealant used where a fire-rated product was needed.
In a village or hamlet like Tyttenhanger, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
There’s a 12-month guarantee on every job, whatever its size.

What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The size of the job
- How many rooms, windows or areas are involved
- Whether there’s mould to deal with
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Signs you need fire rated sealant in Tyttenhanger
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. We see plenty of fire stopping that was hurried, especially where it was squeezed in at the end of a project.
These are the problems we’re asked about most:
- Open holes round services passing through fire walls
- Open gaps behind door architraves
- Standard silicone or caulk in a fire-stopping gap
- Gaps left after a refit or conversion
For landlords with property near St Albans station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Tyttenhanger: your questions answered
Can you do fire rated sealant in Tyttenhanger?
Yes. We work across London and the South East, and Tyttenhanger is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear price.
Is Tyttenhanger within the area you cover?
Yes. Tyttenhanger is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can you give us a record of the work?
Yes. We note each location and the product that went in.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Is the work guaranteed?
Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Tyttenhanger, along with the rest of our area.
Do you seal gaps around fire door frames?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
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.

Flats and HMOs
In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.
What we do, step by step
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes anything from a few hours to several days, depending on how many gaps there are in most cases. Somewhere as small as Tyttenhanger, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your records.
Before we arrive
- Mention any tricky access

What fire rated sealant looks like in Tyttenhanger
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
If you look after a church, hall or community building such as Church of St Mark, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Nicholas Breakspear School? Then service openings in fire-resisting walls need checking after any refurbishment.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Make resealing part of every contractor’s brief
- Report cracked or damaged seals as soon as you notice them
- Plan fire stopping into any work that goes through walls or floors
- Don’t fill fire-stopping gaps with ordinary foam or silicone
Do not add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
