Sites and facades in and around Overton
At about 53 miles from central London, Overton is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Overton sits in one of the drier corners of the country, the South East. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
For contractors at a school such as Overton Church of England Primary School, sealing has to be finished before term starts.

Building work in places the size of Overton is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

What the job involves on each surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

What else we do in Overton
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Overton, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- Tell us your opening times and when work is allowed
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints

Advice
Your questions answered
Is Overton too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
What site paperwork comes with a job in Overton?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
How many days will you need on site?
We plan the time on site around your programme and access. You’ll have an expected duration with the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you provide access for facade work?
We agree access with the client at the start. Let us know what access is in place or planned, and we will price the work around it.
Quoting for work in Overton
A fixed quote reflects the actual work. It allows for:
- Working within restricted access windows
- Which sealant the job calls for
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What we need to price the job
However big the job, the same details help:
- Photos of the joints, close up and from further back
- Whether an asbestos survey exists
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email a schedule or drawings.
Aftercare for building managers
To get the most from the new sealant:
- Investigate damp beside windows promptly
- Share access with other external trades
- Check that rainwater leaves the facade the way it was designed to
- Record the product and colour used on each elevation
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.
For managing agents and facilities managers
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
What we are called out for in Overton
New sealant run over old sealant rarely holds. Cured silicone won’t accept a new silicone bead.
Look out for the following:
- Leaks at window and door perimeters
- Facade joints cracked through the middle
- Old perimeter mastic that has dried out
- Gaps between rainscreen or cladding panels
On any site in or around Overton, the mastic follows the specification and the programme.

- Whether old or failed sealant will be cut out, not overlaid

- How they handle RAMS and site documents
