What window mastic looks like in Sedlescombe

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Durhamford Manor (about 0.7 miles north-west) nearby, there’s older building stock in the area around Sedlescombe as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Schools such as Sedlescombe CofE Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near The Parish Church of St John the Baptist, the joint between an old wall and a newer frame is normally the first place rain gets in.

Window mastic for homes and businesses in Sedlescombe

Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you are dealing with cold air getting in at the frame edge and cracked internal joints between frame and plaster, we can put it right, on patio & French doors, aluminium frames and window sills alike.

Around Sedlescombe, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

A one-year guarantee comes as standard.

Will there be a smell?

What do you put in the joint?

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

How long before the joint can be used?

It depends on the product and the conditions. Before we leave, we will tell you the cure time.

Aftercare tips

So the new joints stay in good condition:

  • Walk round the house once a year and look at the joints
  • Repaint timber before it’s bare
  • Use gentle cleaners on frames and sealant
  • Avoid blasting the frames with a pressure washer

Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.

Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

Common problems we fix in Sedlescombe

Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That is what backing rod is for.

The most common problems we see are:

  • Rushed sealant from a window installation
  • Draughts coming in around windows and doors
  • Gaps between the frame and the inside reveal
  • Water coming in at the bottom corners of a door

For landlords with property near Battle station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Questions to ask before booking

  • Whether they seal over old material or remove it
  • Whether the sealant suits the joint
  • How much experience the applicator has
  • The length of the guarantee

Choosing a sealant specialist

Why deal with it now?

Resealing frames is a short job: it takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around Sedlescombe can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

How we quote for window mastic

For a quick quote, just ask. The main things that affect it are:

  • Whether the work is at height
  • Any mould that needs treating
  • The number of rooms or windows
  • The number and length of the joints

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Helping us quote

To help us quote quickly, please include:

  • Any previous sealing or DIY work
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the job is, and your postcode
  • Pictures of the joints, sent by email

We quote each job on its own, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details.

How it works

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. For a village or hamlet like Sedlescombe, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check each frame and agree which ones need doing.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Where gaps are deep, backing rod goes in first.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Every joint is checked before we leave.

Before we arrive

  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can

DIY versus a professional finish

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

For landlords and businesses

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
