Common questions in Hurstbourne Priors
Can you help a landlord with a rental near Whitchurch (Hampshire) station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Hurstbourne Priors?
Yes, Hurstbourne Priors is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Can you tell me how many minutes the seal will last?
We don’t give ratings or certificates for our work. Your specification sets the requirement, and we apply a product tested for it.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Fire rated sealant in Hurstbourne Priors
Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, and we can record what went where. We work on service penetrations, pipe & cable gaps and door frames, and the jobs we see most are new service routes left unsealed after building work and damaged fire sealant left by other trades.
If you have holiday lets, a converted barn used for business or a community building near Hurstbourne Priors, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What we cannot put right
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

- Fire doors that need new seals, closers or hardware
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Hurstbourne Priors, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Access to each area is agreed so the work can run in order.
- We take out any damaged or unsuitable sealant.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- We record what was done and flag anything that needs a different system.

Why it’s worth doing now in Hurstbourne Priors
For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. Older cottages and farmhouses around Hurstbourne Priors can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

When to call us in Hurstbourne Priors
Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
The most common problems we see are:
- Door frames with gaps between frame and wall
- Gaps where walls meet ceilings or slabs
- Ordinary sealant used where a fire-rated product was needed
- Fire stopping disturbed by later work
Rented homes near Whitchurch (Hampshire) station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Workplaces and buildings in Hurstbourne Priors
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
If you look after a church, hall or community building such as Church of St Andrew, gaps around pipes and cables are worth checking after any building work there. Schools such as Testbourne Community School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
