Your questions answered
Is Long Sutton too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you fit the mastic around our build programme in Long Sutton?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Facade sealing in Long Sutton
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. If you have new sealant peeling off old mastic and facade joints cracked through the middle, we can help. Searching for sealant specialists in Long Sutton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a site near Long Sutton, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photos and the programme and we’ll quote to suit.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

New build and refits around Long Sutton
Long Sutton lies roughly 41 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.
For contractors at a school such as Long Sutton Church of England Primary School, sealing has to be finished before term starts. For a contractor working at a hospital such as Alton Community Hospital, 5.8 miles to the south of Long Sutton, perimeter and facade sealing is planned around patients and deliveries.
Long Sutton is about 5 miles north of Alton, in Hampshire. Anywhere in RG29, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Long Sutton is one of 723 places we cover in Hampshire. Reading is covered too, some 16 miles away.
If you need facade sealing in RG29, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Why act early in Long Sutton
Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Older rural buildings around Long Sutton move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

How the quote is worked out
Your fixed quote is built from the real scope. It allows for:
- Working within restricted access windows
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
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.

- The site address and postcode

- Drawings or a marked-up plan, if available
- What the building is and how it’s used

Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts.

- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full and both faces cleaned back.
- Primer goes on where the product data asks for it.

Advice
Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What else we do in Long Sutton
How the job changes by surface
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
