FAQs for Titmore Green
Is Titmore Green within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Stevenage station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Is the new sealant paintable?
Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.
About our window mastic in Titmore Green
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you’re dealing with mastic that’s falling out in pieces and hard, cracked sealant around windows, we can put it right.
Somewhere as small as Titmore Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Surface by surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Leave it or put it right?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Titmore Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

With historic houses such as Knebworth House (about 3.7 miles south) nearby, there’s older building stock in the area around Titmore Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

Do you need window mastic in Titmore Green?
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Most people get in touch after spotting one of these:
- Cold air getting in at the frame edge
- White mastic on grey or black frames
- Mastic that is falling out in pieces
- Cracked or shrunken mastic around the frame
In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. In a small place like Titmore Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Mention if the joints have been sealed before

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Ventilate rooms so frames do not stay wet inside
- Avoid blasting the frames with a pressure washer
- Don’t use solvent cleaners on the joint
- Check the mastic once a year
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
