What affects the cost of window mastic
Every job gets its own quote. These are the things that affect it:
- How much there is to do
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The number of rooms or windows
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
You do not need to know the technical terms. Just tell us:
- Whether it’s a home or a business
- The address or postcode of the job
- Photos by email, if that’s easy

Window mastic for homes and businesses in Frilsham
Around Frilsham we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have rushed sealant from a window installation and black, perished sealant on frames, we can put it right, on aluminium frames, uPVC windows and patio & French doors alike.
Mastic can only go onto a dry, clean joint, so window work in Frilsham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Landlord and commercial work in Frilsham
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

When to call us in Frilsham
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Common reasons people contact us include:
- Gaps left after new windows were fitted
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
- Whistling draughts around closed windows
Managing a site like Yattendon C.E. Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.
Before booking anyone
- Whether they’re fully insured
- Is the old sealant removed completely?
- Whether you can choose the colour
- How the surfaces are prepared before sealing
Frilsham homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Midgham station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St Frideswide include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Frilsham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on

Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does it take to reseal the windows on a house?
Allow anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Surface by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
