When to call us in Hurstbourne Priors
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
What tends to prompt an enquiry:
- No planned programme for sealant
- Old repairs sealed over failed mastic
- Leaks at window and door perimeters
- Cracked, hardened mastic round windows on a block
For a school such as Testbourne Community School, perimeter mastic on windows and doors is a holiday job.

On site: what to expect

On site, the work typically takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. If others near Hurstbourne Priors need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

Your questions answered
Is Hurstbourne Priors too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Can you work at a site such as Ardglen Industrial Estate, by Hurstbourne Priors?
Yes. Estates, retail parks and business parks around Hurstbourne Priors, Ardglen Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
How long does a typical visit take?
That varies with the scale of the job, but the work usually takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
What paperwork can you provide?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Have the asbestos survey to hand for older buildings
- Start inspections with the most exposed faces
- Track which buildings were done and when
- Mention RAMS, insurance or CSCS requirements up front
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.
When to bring in a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When something else is needed
Honesty saves time and money. New sealant won’t cure:
- Leaks from above rather than through a joint
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.
