Window mastic for homes and businesses in Stubbles
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. If you have gaps where the sill meets the wall and water coming in at the bottom corners of a door, we can help, whatever the surface.
Around Stubbles, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same 12-month guarantee in Stubbles and across Oxfordshire.

Window mastic in Stubbles: local notes
With historic houses such as Basildon Park (about 2.5 miles north-east) nearby, there’s older building stock in the area around Stubbles as well as newer homes. 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of St Clement, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Goring & Streatley station, renewing tired window mastic between tenants heads off draught and damp complaints.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Wash the frames with mild soapy water
- Keep solvents and bleach off the sealant
- Air rooms to keep condensation down around windows
- Paint up to the joint, not over it
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Quotes for window mastic in Stubbles
There’s no set price list. The quote depends on:
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- How easy the joints are to reach
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- What’s wrong with the joints now
- Where the property is
- If it’s domestic, commercial or a hotel
Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Questions from Stubbles
Is Stubbles within the area you cover?
Yes, Stubbles is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
I let a flat near Goring & Streatley station. Can you help?
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’ll give you a fixed price before work begins.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Where are you based?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
How the job changes by surface
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 suits the frame.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
The process
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take a morning for a couple of windows and a door, and we explain the cure time before we leave. In a small place like Stubbles, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit

Why it’s worth doing now in Stubbles
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like Stubbles, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
