About our window mastic in Broxhill
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. If you have cracked internal joints between frame and plaster and mastic that’s falling out in pieces, we can put it right, on composite doors, aluminium frames and timber windows & doors alike.
Homes in small places like Broxhill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Broxhill and everywhere else we cover.

Other services in Broxhill
Different surfaces, different methods
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
Landlord and commercial work in Broxhill
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes most of a day for a typical house, less for a few frames, depending on the size of the job. In a small place like Broxhill, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Keep children and pets away from the work area

Common questions in Broxhill
Is window mastic in Broxhill guaranteed?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will you come out to Broxhill?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you match the sealant to my frames?
Yes, in most cases. Tell us the frame colour when you get in touch and we will match it as closely as we can.
Do you work for landlords and businesses?
Yes, we do. We work in homes, commercial premises and hotels.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What affects the quote in Broxhill
Your quote is based on your job. We look at:
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- How many rooms, windows or areas are involved
- The number and length of the joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- If someone has resealed it before
Call for a quick quote, or email us if that is easier. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear price.
Why act early in Broxhill
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, using a product chosen for the frame and wall. Where a wall is exposed, as many are in small places like Broxhill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Windows and doors in Broxhill
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. In and around Broxhill, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
