Window mastic in Liverton Street

Homes in Liverton Street have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you are dealing with gaps left after new windows were fitted and cracked sealant at the sill ends, we can put it right, on timber windows & doors, window sills and aluminium frames alike.

Around Liverton Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

There’s a 12-month guarantee on every job, large or small.

It helps to know what we can’t do too:

Liverton Street homes and the weather

With historic houses such as Leeds Castle (about 3.1 miles north-west) nearby, there’s older building stock in the area around Liverton Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Managing a site like Platts Heath Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Lenham station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of St Nicholas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Your questions about window mastic in Liverton Street

Will you come out to Liverton Street?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you work for landlords with property near Lenham station?

Yes, we work for landlords and letting agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you when we finish.

How do I get a quote for window mastic in Liverton Street?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

Is it OK to seal over old sealant?

No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint.

Do you have insurance?

Yes. We’re fully insured.

Can you seal the gap between the frame and the plaster indoors?

Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.

Why deal with it now?

Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Liverton Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why choose Mr Mastic in Liverton Street

How we quote for window mastic

The price is agreed before any work begins. It takes into account:

  • Working hours on commercial sites
  • How many rooms, windows or areas are involved
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out

We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Asking for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is
  • Any access issues, like height or stairs
  • Whether it’s a home or a business

Need a quote? Please phone 0345 464 0079 or send us an email and tell us about the job. We will explain what we’d do and give you a clear price before we start.

Keeping the joints in good condition

Good habits help new joints last longer. A few tips:

  • Ventilate rooms so frames do not stay wet inside
  • Keep jet washers away from the mastic
  • Repaint timber before it’s bare
  • Check the mastic once a year

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.

Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

Different surfaces, different methods

uPVC windows

Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.

Window sills

Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.

How it works

You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. In a small place like Liverton Street, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check each frame and agree which ones need doing.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Finally we tidy up and check each joint.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Tell us if parking is tricky
  • Keep pets and children clear of the area while we work

Ask for a quote

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, call 0345 464 0079 or send us an email.
