Window Mastic in Elvetham Heath
Our applicators work in Elvetham Heath on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
Window mastic in Elvetham Heath, done properly
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. If you’re dealing with white mastic on grey or black frames and mastic that has split away from the wall, we can help.
Homes around Elvetham Heath range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Every job comes with our 12-month guarantee.

Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.

What else we do in Elvetham Heath
Elvetham Heath: your questions answered
Is Elvetham Heath within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Fleet station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.
Do you have insurance?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Can new window sealant be painted?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What we do, step by step
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door, and the area is left clean. Parking around Elvetham Heath is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Mention any parking rules near the property

Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Housing providers, facilities teams and property managers book us too in Elvetham Heath and across Hampshire. Several sites can be quoted together, and we are fully insured for the work.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Ventilate rooms so frames don’t stay wet inside
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Do not aim a pressure washer at the joints
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
Elvetham Heath homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Fleet station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Elvetham Heath Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What we’re called out for in Elvetham Heath
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Keep an eye out for any of the following:
- Old mastic that has gone black or come away
- Cold air getting in at the frame edge
- A bead that doesn’t match the frame
- Leaking joints at the ends of sills
If you live in an older home near Church on the Heath, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
