Loxford questions

I let a flat near Barking station. Can you help?

Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.

Do you work for hotels and guest houses in Loxford?

Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can I add another job to the visit?

Yes, we can. Several rooms, windows or areas can go on one quote.

Do you carry out fire risk assessments?

No, we do not assess buildings. Once you have a specification or action list from your assessor or designer, we can quote for the fire-rated sealant items.

How long will you be here?

Typically it takes from a few hours to a few days, depending on the number of gaps and the access. Bigger jobs take longer.

Do you have insurance?

Yes. We’re fully insured for every job we do.

Can I use normal mastic around a pipe through a fire wall?

No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.

Fire rated sealant for homes and businesses in Loxford

Door frame gaps, linear joints and holes around services all have their own details. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We are often asked to deal with open gaps behind door architraves and fire stopping disturbed by later work, across door frames, service penetrations and pipe & cable gaps.

In London, a commercial job often starts with access: loading bays, building rules and lifts. For a building in Loxford, we agree timings and access before anything starts.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Different surfaces, different methods

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. The sealant has to be one tested in plasterboard for the gap we’re sealing.

Door frames

A door can only do its job if the gap behind its frame is sealed too. We seal that gap with a fire-rated sealant suited to the frame and wall.

Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Loxford.

Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Fire rated sealant around Loxford

Loxford has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.

Schools such as Woodlands Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in. For landlords with property near Barking station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. Community buildings like St Luke's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What happens on the day

We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. In Loxford, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your records.

How to prepare

  • Mention if the joints have been sealed before
  • Tell us about any water getting in
  • Tell us if parking is tricky

How to get a quote

Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand.

Advice

What affects the quote in Loxford

Your quote is based on your job. We take into account:

  • How many areas need sealing
  • How much there is to do
  • Working hours on commercial sites
  • The product the joint needs

The cost depends on the size of the job, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.

Helping us quote

Photos by email are helpful but not essential. Please mention:

  • The type of property
  • A few pictures by email, if you can
  • Where the property is
  • Whether it has been sealed before

For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved.

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Keeping the joints in good condition

Aftercare is simple, and it makes a real difference:

  • Check risers, ceiling voids and cupboards during building checks
  • File the fire-stopping record where your assessor can find it
  • Make resealing part of every contractor’s brief
  • Never patch a fire seal with standard sealant

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 sealant work cannot fix

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

  • Deciding what fire stopping a building needs
  • Doors that are not fire doors in the first place
  • A wall that is not a fire-resisting element to begin with

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.
