Frames and glazing around Hawley
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Blackwater station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Holy Trinity Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Hawley Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Window mastic in Hawley, done properly
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, window sills and timber windows & doors, and common reasons people get in touch are water coming in at the bottom corners of a door and black, perished sealant on frames.
In smaller places like Hawley, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
There’s a 12-month guarantee on every job, large or small.

The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from an hour or two to a full day, depending on how many frames there are. For a job in Hawley, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

What happens if it’s left?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Hawley, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.

Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.

What else we do in Hawley
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Hawley questions
Do you cover Hawley for window mastic?
Yes. We work across London and the South East, and Hawley is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear quote.

Are you ARBOMaster approved?
Yes. We are approved under the ARBOMaster scheme.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
When something else is needed
A few problems are outside what sealant work can do:
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
- Rotten timber, which needs a joiner first
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.
