About our window mastic in Hatford
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. Common call-outs are for sealant in the wrong colour for the frame and gaps between the frame and the inside reveal, on uPVC windows, patio & French doors and window sills.
Homes in small places like Hatford often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Your job is guaranteed for a year, as with all our work.

Common problems we fix in Hatford
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
Any of these means the joints need attention:
- Mastic that has split away from the wall
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
- Gaps between the frame and the inside reveal
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.

For landlords and businesses
Housing providers, facilities teams and property managers book us too in Hatford and across Oxfordshire. Several sites can be quoted together, and we’re fully insured.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What affects the cost of window mastic
Your quote is based on your job. We look at:
- The number and length of the joints
- Which sealant suits the joint
- The number of rooms or windows
- Working hours on commercial sites
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Helping us quote
What to tell us when you ask for a quote:
- The problem you’ve noticed
- The type of property
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, phone 0345 464 0079 or send us an email.
Aftercare tips
So the new joints stay in good condition:
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
The process
All our tools and materials come with us in the van. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a handful of frames, longer for a whole house. Somewhere as small as Hatford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Surface by surface
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
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.
Frames and glazing around Hatford
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. Historic houses like Longworth House (about 3.9 miles north-east) are a reminder that the area around Hatford has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Stanford in the Vale Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.
