Alfriston questions

Is Alfriston within the area you cover?

Yes, Alfriston is covered. 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.

Can you help a landlord with a rental near Berwick (Sussex) station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.

Will the old sealant be removed?

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

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little.

How long will you be here?

It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We will give you a better idea when we quote.

Can new sealant go over the old?

No. The old sealant always comes out first.

Is there a guarantee?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Will we have a record of what was sealed?

Yes. We note each location and the product that went in so it’s there for the next inspection.

What affects the quote in Alfriston

Call for a quick quote. The main things that affect it are:

  • Any mould that needs treating
  • The number and length of the joints
  • Which sealant suits the joint
  • The number of rooms or windows

Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What we need to know

To help us quote quickly, let us know:

  • What’s wrong with the joints now
  • How we’d reach the joints
  • Whether it’s a home or a business
  • Roughly how big the job is

Getting a quote is simple: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Common problems we fix in Alfriston

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The most common problems we see are:

  • New service routes left unsealed after building work
  • Old fire sealant that has split or come away
  • Linear gaps at the head of walls
  • Joints picked up in a fire-stopping survey

For buildings such as Church of St. Andrew, gaps around pipes and cables are worth checking after any building work there.

10 questions to ask before you book

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

When something else is needed

A few problems are outside what sealant work can do:

  • Issuing a fire rating or certificate for a building
  • Big openings where sealant alone isn’t the tested solution
  • Deciding what fire stopping a building needs

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

Joints and surfaces we work on

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

What the job involves on each surface

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes are not treated the same. Each one is sealed to the product’s tested detail.

How it works

At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes anything from a few hours to several days, depending on how many gaps there are, depending on the size of the job. In a small place like Alfriston, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We go through the gaps on your list or survey and check each one’s size and substrate.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. We record the locations and products used for your records.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Let us know about parking restrictions
  • Move anything stored near the joints
