How the job changes by surface
Plasterboard walls
Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for the gap we’re sealing.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required before the sealant goes in.

Aston End questions
Is Aston End within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Stevenage station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Are you fully insured?
Yes. Full insurance covers our work.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
Fire rated sealant in Aston End: local notes
Stevenage, which Aston End is part of, is one of England’s post-war new towns. Stevenage was planned with its own industrial and business areas, so workplaces sit close to the homes. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. 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 building such as Ashtree Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices. Community buildings like Parish Church of St Mary the Virgin are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For landlords with property near Stevenage station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
Aston End is about 1 mile east of Stevenage, in Hertfordshire. Our applicators cover fire rated sealant for homeowners, landlords and businesses in Aston End and nearby. Aston End is one of 381 towns and villages in Hertfordshire we cover. For nearby work, see our London page (28 miles or so).

Why act early in Aston End
Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job. Older cottages and farmhouses around Aston End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Store the list of sealed gaps with your building paperwork
- Tell trades working in the building that fire seals must be put back
- Check whether a sealant can be painted before decorating over it
- Check risers, ceiling voids and cupboards during building checks
Any fire seal that is cut or drilled needs resealing to its tested detail. New services through a sealed wall should include fire stopping in the plan.
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.

What we can’t put right
To be straight with you, some problems need a different trade:
- A wall that isn’t a fire-resisting element to begin with
- Openings too large for sealant, which need batts, boards or another system
- Deciding what fire stopping a building needs
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Surfaces we seal

What we do, step by step
The work is kept neat and contained to the joints we’re treating. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access.

Everything for the job comes with us, so a second trip is avoided where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
How to prepare

How we quote for fire rated sealant
Your quote is based on your job. We take into account:
- Whether the work is at height
- The amount of work
- The product the joint needs
- Any working-time requirements on site
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- The rough size of the job
- The type of property
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
