Questions from Springvale
Do you cover Springvale for window mastic?
Yes, Springvale is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
I let a flat near Winchester station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
How long will my window job take?
The work takes a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Where are you based?
We are a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can I paint over the new sealant?
Not normally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Window mastic for homes and businesses in Springvale
Homes in Springvale have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, uPVC windows and aluminium frames, and common reasons people get in touch are black, perished sealant on frames and hard, cracked sealant around windows.
In a smaller place like Springvale, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Quotes for window mastic in Springvale
We quote each job individually. This is what makes a difference:
- The product the joint needs
- When we can work, for business premises
- How many areas need sealing
- Whether the work is at height
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Pictures of the joints, sent by email
- The rough size of the job
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
When it is not the sealant
In fairness, some problems need a different trade:
- Condensation trapped between the panes
- Penetrating damp from a failed cavity tray or render
- Broken hinges, locks or handles
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer before booking.

Can I do it myself?
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, 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.
The process
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. In a smaller place like Springvale, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

What happens if it’s left?
The work is quick compared with the damage it prevents: the visit takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. In an older home around Springvale, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.

Window mastic in Springvale: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as St Mary's Church Hall, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Kings Worthy Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Winchester station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

How the job changes by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall and tooled smooth.
