Window & door mastic in Shalcombe, Isle of Wight
Problem with your window and door frames in Shalcombe? We cut out the old, prepare the joints and apply the right sealant.
- A bead that does not match the frame
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic in Shalcombe
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you are dealing with cracked internal joints between frame and plaster and white mastic on grey or black frames, we can put it right, whatever the surface.
Mastic can only go onto a dry, clean joint, so window work in Shalcombe is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work comes with our 12-month guarantee, wherever you are in the Isle of Wight.

Windows and doors in Shalcombe
Shalcombe is within about 2 miles of 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. With historic houses such as Mottistone Manor (about 1.3 miles south-east) nearby, there’s older building stock in the area around Shalcombe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around St. Mary's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

What we are called out for in Shalcombe
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
The problems people generally mention when they call are:
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Mastic that has split away from the wall
Around Shalcombe, as everywhere, window mastic is only as good as the preparation behind it.

What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Why act early in Shalcombe
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. In a small place like Shalcombe, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

FAQs for Shalcombe
Do you cover Shalcombe for window mastic?
Yes. We work across London and the South East, and Shalcombe is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is Shalcombe within the area you cover?
Yes, Shalcombe 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 reach windows above the ground floor?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
What happens on the day
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take a morning for a couple of windows and a door. In a small place like Shalcombe, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Tell us if parking is tricky
- Mention any tricky access
- Let us know about earlier repairs to the joints
