Window mastic for homes and businesses in Widley
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on window sills, patio & French doors and uPVC windows, and the jobs we see most are cold air getting in at the frame edge and gaps left after new windows were fitted.
Mastic can only go onto a dry, clean joint, so window work in Widley is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Your job is guaranteed for a year, as with all our work.

Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will talk you through the work before giving you a price.
How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. Most jobs take most of a day for a typical house, less for a few frames. For a village or hamlet like Widley, 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.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts
- Move anything stored near the joints
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Repaint timber before it’s bare
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
- Don’t paint over the silicone
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What we are called out for in Widley
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
For landlords with property near Cosham station, renewing tired window mastic between tenants heads off draught and damp complaints.

Frames and glazing around Widley
Widley is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Christ Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Purbrook Park School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
Widley is about 1 mile south-west of Purbrook, in Hampshire. Homes, rented property, offices and hotels in Widley is covered for window mastic, old or new, large or small. The work is guaranteed for a year. Widley is one of 683 towns and villages in Hampshire we cover.

Questions from Widley
Is Widley within the area you cover?
Yes, Widley is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Cosham station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
Are you fully insured?
Yes. We are fully insured for domestic and commercial work.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Will resealing my frames help with draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you have sealant for grey or black windows?
Yes. Anthracite grey, black, brown and white cover most frames, with clear as an option.
How long does it take to reseal the windows on a house?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
Why deal with it now?
The work is quick compared with the damage it prevents: the visit 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. Around Widley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. 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. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Different surfaces, different methods
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
