Trusted fire rated sealant in Sunningwell

What sealant work cannot fix

We will not take on work that won’t last, so these are the limits:

  • Fire doors that need new seals, closers or hardware
  • A wall that is not a fire-resisting element to begin with
  • Big openings where sealant alone isn’t the tested solution

If you’re not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Plasterboard & masonry
  • Linear gaps
  • Door frames
  • Service penetrations
  • Pipe & cable gaps
  • Flats & HMOs

Fire rated sealant in Sunningwell

Deciding which gaps need fire stopping is not our role; your assessor, designer or building control sets that out. What we do is apply the right product to that specification, properly and neatly. If you have open holes round services passing through fire walls and new service routes left unsealed after building work, we can help, whatever the surface.

Somewhere as small as Sunningwell, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Every job is covered by a 12-month guarantee, wherever you are in Oxfordshire.

Landlord and commercial work in Sunningwell

For anyone letting property in or around Sunningwell, several properties can go on one quote. Just tell us the addresses and what each one needs.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

FAQs for Sunningwell

Can you help a landlord with a rental near Radley station?

Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.

Will you come out to Sunningwell?

Yes, Sunningwell is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Is the work guaranteed?

Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.

Can you match the sealant colour?

Most of the time, yes. We will explain which colours are available and agree one before any work starts.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Will the old sealant be removed?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Do you provide details of the products used?

Yes. We note each location and the product that went in.

What’s the difference between intumescent and fire-rated sealant?

Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.

What affects the quote in Sunningwell

Call for a quick quote. What matters most is:

  • The product the joint needs
  • Working hours on commercial sites
  • The number of rooms or windows
  • Any mould that needs treating

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

Helping us quote

Photos help, but a description is a good start. Please mention:

  • Any access issues, like height or stairs
  • Where the property is
  • The type of property
  • The rough size of the job

To get a quote, phone 0345 464 0079 or email us and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.

Can I do it myself?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What the job involves on each surface

Door frames

Our work is the joint between frame and wall. Doors, seals and closers are for a door specialist.

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.

How it works

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access, and the area is left clean. Somewhere like Sunningwell needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that isn’t fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

How to prepare

  • Clear the area around the work
  • Try not to wet indoor joints just before the visit
  • Mention any parking rules near the property

Getting a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or send us an email.

Advice

Fire rated sealant in Sunningwell: local notes

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 let a flat or house near Radley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of St Leonard, service openings in its walls need the right fire-rated sealant, as in any building. For site and facilities teams at buildings such as Sunningwell Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Ask which product was used before you paint
  • Ask every contractor to reseal any fire stopping they disturb
  • Plan fire stopping into any work that goes through walls or floors
  • Get damaged fire seals looked at promptly

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.
