Why act early in Lower Titmore Green
Draughts round window perimeters cost occupiers comfort and the windows normally get the blame. Resealing the perimeters is often the simpler fix when the frames themselves are sound. Halls, stores and units around places like Lower Titmore Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Why us?
- A Constructionline member, so easy to vet
- Commercial sealant work since 2005
- Work carried out by CSCS-carded applicators
- Standard and matched colours in many product ranges
Site staff or a sealant specialist?
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For work around Lower Titmore Green, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

Lower Titmore Green: questions and answers
Can you quote for a block close to Stevenage station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Is a smaller place like Lower Titmore Green outside your area?
No. Places such as Lower Titmore Green are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Ask residents or tenants to report leaks and draughts early
- Keep bins and bikes away from communal door frames
- Plan resealing building by building rather than complaint by complaint
- Check the asbestos register before any old mastic is disturbed
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.
The longer failed joints are left, the more likely the substrate edges break up. Then the edges may need repairing first and the job grows.
Signs you need mastic sealing in Lower Titmore Green
Occasionally the substrate fails, not the sealant, such as crumbling render, brick arrises or frame edges. If the edges are unsound, we say so before quoting the sealing.
Things that normally lead to an enquiry:
- Window mastic that has split and shrunk
- Old repairs sealed over failed mastic
- No planned programme for sealant
- Failed external movement joints
If your remit includes a building such as Wymondley Junior Mixed and Infant School, frame and door mastic can be programmed for the holidays.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
