Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
How we handle window mastic in Frimley
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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on window sills, patio & French doors and composite doors, and the jobs we see most are leaking joints at the ends of sills and white mastic on grey or black frames.
In a town like Frimley, older houses sit alongside newer estates, with windows of every age. All of them depend on a sound bead of mastic between frame and wall.
You get a one-year guarantee, the same in Frimley as everywhere else we work.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Paint up to the joint, not over it
- Ventilate rooms so frames do not stay wet inside
- Look round the frames every year or so
- Wash the frames with mild soapy water
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Frimley homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around St. Peter's Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Frimley station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What affects the quote in Frimley
The price is agreed before any work begins. It takes into account:
- The product the joint needs
- Mould in or behind the old joints
- Working hours on commercial sites
- The size of the job
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we’ll talk you through it.
Helping us quote
When you call or email, these details help:
- The address or postcode of the job
- The type of property
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or email us.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
For anyone letting property in or around Frimley, several properties can be quoted together. Just tell us the addresses and what each one needs.
What happens on the day
You do not need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. In Frimley, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Clear items away from the joints we’re working on
- Mention if the joints have been sealed before
- Let us know about parking restrictions

What we are called out for in Frimley
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That’s what backing rod is for.
Any of these means the joints need attention:
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
Schools such as Lakeside Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- What guarantee comes with the work
- What insurance they hold
- When the joint can take water or movement
- How hidden problems are handled

When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:

- A frame that has rotted at the joint
- A sash or casement that will not close properly
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Patio & French doors
- Window sills
- uPVC windows
- Composite doors

Common questions in Frimley
Can you do window mastic in Frimley?
Yes, Frimley is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Is there a guarantee on window mastic in Frimley?
Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Can new sealant go over the old?
No, it will not last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
Can you do upstairs windows?
Yes, in most cases. We plan safe access before the job.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
