What we do, step by step

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a handful of frames, longer for a whole house. In a small place like Corhampton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Clear the area around the work
  • Let us know if you’ve seen damp or leaks

Advice

Window mastic in Corhampton: local notes

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hinton Ampner House (about 4.4 miles north) are a reminder that the area around Corhampton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

For an older house near a landmark such as Corhampton Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Corhampton is about 7 miles north-west of Horndean, in Hampshire. Corhampton gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Across Hampshire, we cover 683 places, and Corhampton is one of them. For nearby work, see our Southampton page.

What we are called out for in Corhampton

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.

People usually contact us when they notice one of these:

  • Leaking joints at the ends of sills
  • Draughty joints inside around the window
  • Draughts coming in around windows and doors
  • Water coming in at the bottom corners of a door

Managing a site like Meonstoke Church of England Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Choosing a sealant specialist

What we cannot put right

A few problems are outside what sealant work can do:

  • Worn gaskets, brush seals or a door that has dropped
  • Damp problems in the wall away from the window
  • Broken hinges, locks or handles

If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

  • Composite doors
  • Timber windows & doors
  • uPVC windows
  • Aluminium frames
  • Window sills
  • Patio & French doors

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Keep paint off silicone joints
  • Check the mastic once a year
  • Wipe condensation off the frames
  • Keep solvents and bleach off the sealant

Silicone can’t normally be painted, so mention any painting plans before we start. We can use a paintable sealant where that matters.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.

Questions from Corhampton

Is window mastic in Corhampton guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Can you do window mastic in Corhampton?

Yes, Corhampton is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will send you a clear quote.

When is the sealant fully cured?

Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.

Do you seal inside as well as outside?

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

Is it messy?

We keep the work tidy. We protect what’s around the joints.

How many windows can you do in a day?

A few frames take a few hours, while a whole house takes longer. You will get a timescale with the quote.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Get your landlord’s agreement first.

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

Surface by surface

Window sills

Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Leave it or put it right?

The work is quick compared with the damage it prevents: 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 Corhampton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.
