Window Mastic in Great Bentley
Mastic around window and door frames, sills and patio doors for homes and businesses in Great Bentley and across Essex. ARBOMaster approved applicators, fully insured, with a one-year guarantee.

How we handle window mastic in Great Bentley
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. If you have draughty joints inside around the window and untidy mastic left by window fitters, we can help, on aluminium frames, timber windows & doors and patio & French doors alike.
Around Great Bentley, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
There’s a 12-month guarantee on every job.

Great Bentley homes and the weather
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Thorpe Hall (about 4.4 miles east) nearby, there’s older building stock in the area around Great Bentley as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Great Bentley Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens on the day
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes most of a day for a typical house, less for a few frames from start to finish. For a job in Great Bentley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- 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.
- Every joint is tooled smooth and checked before we leave.

Common questions in Great Bentley
Can you help a landlord with a rental near Great Bentley station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Great Bentley in your area for window mastic?
Yes, Great Bentley is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you get sealant to suit coloured frames?
Normally, yes. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
How do I get a quote for window mastic in Great Bentley?
Size, access and the old material all affect the cost. Ask us for a quote.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before we start.
Signs you need window mastic in Great Bentley
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
It’s worth asking for a quote if you see:
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
For landlords with property near Great Bentley station, renewing tired window mastic between tenants heads off draught and damp complaints.
Before you book anyone
- Whether VAT is included
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- Who does the work, and how experienced they are
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What affects the quote in Great Bentley
For a quick quote, just ask. What matters most is:
- When we can work, for business premises
- Which sealant suits the joint
- Access and height
- How many areas need sealing
Every job is a little different, so we quote each one individually. 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.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- How we’d reach the joints
- Whether it’s a home or a business
- Where the property is
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.
What the job involves on each surface
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.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
