Window mastic in Frithend, done properly
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for whistling draughts around closed windows and gaps left after new windows were fitted, on window sills, uPVC windows and aluminium frames.
Mastic can only go onto a dry, clean joint, so window work in Frithend 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.

What affects the cost of window mastic
Call for a quick quote. The main things that affect it are:

- How much there is to do
- Access and height
- Which sealant suits the joint
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Why it’s worth doing now in Frithend
Resealing frames is a short job: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Around Frithend, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.
Why book with us
- Colour agreed with you before any work starts
- ARBOMaster approved applicator
- A choice of colours where the product allows
- 4.9 on Google from 180+ five-star reviews

Window mastic in Frithend: local notes
Historic houses like Farnham Castle (about 4.8 miles north-east) are a reminder that the area around Frithend 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as The Church Of The Good Shepherd, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes most of a day for a typical house, less for a few frames. Somewhere like Frithend needs a little journey planning: 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 start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Advice
Do you need window mastic in Frithend?
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Keep an eye out for these signs:
- Black, perished sealant on frames
- Gaps left after new windows were fitted
- Gaps between the frame and the inside reveal
- Whistling draughts around closed windows
Letting a property close to Bentley (Hampshire) station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What your quote should include
- Is VAT in the price?
- Whether all the old sealant comes out first
- Who does the work, and how experienced they are
- What product goes in the joint
Your questions about window mastic in Frithend
I let a flat near Bentley (Hampshire) station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Frithend?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Surface by surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Composite doors
A composite door usually sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
