Tyttenhanger: your questions answered
I let a flat near St Albans station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Tyttenhanger?
Yes. Tyttenhanger is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we’ll quote it together.
Can you get sealant to suit coloured frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
How long does it take to reseal the windows on a house?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Window mastic for homes and businesses in Tyttenhanger
Every window and door frame has a gap around it, and mastic is what closes it. 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’re dealing with white mastic on grey or black frames and black, perished sealant on frames, we can put it right, whatever the surface.
Somewhere as small as Tyttenhanger, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our 12-month guarantee.

What happens if it’s left?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In a small place like Tyttenhanger, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Tyttenhanger homes and the weather
With historic houses such as Batchwood Hall (about 3.3 miles north-west) nearby, there’s older building stock in the area around Tyttenhanger as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near St Albans station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Nicholas Breakspear School, its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.

Do you need window mastic in Tyttenhanger?
Joints that are too thin or too deep fail early. 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.
These are the problems we’re asked about most:
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Black, perished sealant on frames
- Draughts coming in around windows and doors
For an older house near a landmark such as Church of St Mark, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Before you book anyone
- Whether you can choose the colour
- Which sealant they’ll use, and why
- What happens if the job turns out different
- Whether they seal over old material or remove it
What we cannot put right
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant will not put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A frame that has rotted at the joint
- A sash or casement that will not close properly
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Aluminium frames
- uPVC windows
- Window sills
- Timber windows & doors
- Composite doors
- Patio & French doors
For landlords and businesses
For anyone letting property in or around Tyttenhanger, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. Somewhere like Tyttenhanger needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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.
Before we arrive
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
