DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
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, and the work is guaranteed for a year.
Window mastic in Emmbrook, 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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you have white mastic on grey or black frames and cracked internal joints between frame and plaster, we can help, on composite doors, uPVC windows and timber windows & doors alike.
In a smaller place like Emmbrook, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Signs you need window mastic in Emmbrook
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Common reasons people contact us include:
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Mastic that’s falling out in pieces
- Leaking joints at the ends of sills
For an older house near a landmark such as Woosehill Community Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Emmbrook
Can you help a landlord with a rental near Wokingham station?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Will you come out to Emmbrook?
Yes. Emmbrook is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or drop us an email.
Do you have insurance?
Yes. Full insurance covers our work.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Do you work on first-floor windows?
Generally, yes. Access is planned before we start, so mention the height and anything in the way.
What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal

- When we can work, for business premises
- The number and length of the joints
- Access and height
- How many areas need sealing
Doing several joints on one visit is generally more efficient than separate visits. We will send you a clear quote for the lot.

For a quote, call 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We’ll give you a clear price before any work starts.
Frames and glazing around Emmbrook
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.
Managing a site like Emmbrook Infant School? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Wokingham station, renewing tired window mastic between tenants heads off draught and damp complaints.

Surface by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Why act early in Emmbrook
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In an older home around Emmbrook, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why us?
- Full insurance on every job
- Old sealant always removed completely
- You choose the colour before work begins
- Homes, businesses and hotels

What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. In a smaller place like Emmbrook, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each window and door with you.
- 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 any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
