Can I do it myself?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Landlord and commercial work in Kemsley

Letting agents and landlords in Kemsley can book us as well as householders. Sealant work between tenants keeps a property looking cared for.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Ask which product was used before you paint
  • File the fire-stopping record where your assessor can find it
  • Ask every contractor to reseal any fire stopping they disturb

Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.

Common questions in Kemsley

Do you work for hotels and guest houses in Kemsley?

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Is Kemsley within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you certify the fire stopping?

Ratings and certificates aren’t something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves, and we install to them.

How long does the job take?

Typically it takes anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we’ll tell you how long to expect.

Do you remove the old sealant?

Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Where are you based?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.

Different surfaces, different methods

Door frames

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

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first.

What we are called out for in Kemsley

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. We see plenty of fire stopping that was hurried.

These are the problems we’re asked about most:

  • Unsealed gaps around fire door frames
  • Gaps where walls meet ceilings or slabs
  • Cracked or shrunken fire-rated sealant
  • Holes left by a change of layout

Community buildings like Parish Church of the Holy Trinity are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

What to look for in a quote

  • How the surfaces are prepared before sealing
  • How much experience the applicator has
  • What the cure time is
  • How the colour is chosen

What happens if it’s left?

Waiting for the next refit can leave a gap open for years. On its own, sealing it now is a small job and needn’t wait for anything else. Around Kemsley, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, phone 0345 464 0079 or email us and we will give you an honest view and a quote.

The process

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It usually takes a few hours for a handful of gaps, and longer for a whole building. For a job in Kemsley, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Backing or fill is fitted where the product’s tested detail calls for it.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Locations and products are noted so you have them on file.

Before we arrive

  • Clear items away from the joints we’re working on
  • On commercial sites, let us know about site rules
  • Let us know about parking restrictions
