Remedial sealant in Upper Heyford

Why deal with it now?

Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Homes in smaller places like Upper Heyford can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Remedial sealant for homes and businesses in Upper Heyford

Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. When the fault is elsewhere, we say so instead of resealing for the sake of it. Common call-outs are for beads that never stuck properly and thick, messy sealant smeared over tiles, across leaking tray & enclosure joints, mouldy bath & shower sealant and shrunken worktop sealant.

Around Upper Heyford, you’ll mostly find houses and bungalows, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Looking after it afterwards

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Use a soft cloth, not a scourer, on silicone
  • Keep the room well ventilated
  • Always have old sealant cut out, not covered
  • Don’t wait for a small gap to become a leak

Don’t let anyone seal over it later. New silicone does not bond to old.

Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

What remedial sealant looks like in Upper Heyford

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.

Homes close to Heyford Park Chapel include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Heyford station, a joint that keeps failing is best fixed properly while the property is empty.

Surface by surface

Windows & doors

Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.

Leaking trays & enclosures

Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.

For landlords and businesses

For anyone letting property in or around Upper Heyford, several properties can be quoted together. Just tell us the addresses and what each one needs.

Landlords and agents in Upper Heyford can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

The process

We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most joints, depending on how much old sealant has to come out. Parking around Upper Heyford is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Each layer is cut out and the residue cleaned off.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. The joint is tooled and you are told about anything else we found.

How to prepare

  • Mention if the joints have been sealed before
  • Plan for the work area to be out of bounds to pets and children
  • Try not to wet indoor joints just before the visit

Advice

Questions from Upper Heyford

Do you work for landlords with property near Heyford station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.

Is Upper Heyford in your area for remedial sealant?

Yes. Our work covers London and the South East, and Upper Heyford is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Do you offer different sealant colours?

Most of the time, yes. We will tell you which colours the right product comes in and agree one before we start.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit.

Which products do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

My shower still leaks after a reseal. Can you sort it?

Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.

Where is Mr Mastic based?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Can you remove sealant that is been put over old sealant?

Yes. Both layers come out; new silicone doesn’t bond to old silicone, which is why over-sealing fails.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

A careful DIYer can reseal a simple joint, 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.
