Construction mastic in Maplehurst, done properly
Mastic tends to be one of the final packages before handover. Mastic Doctor takes on mastic packages for main contractors and developers. If you are dealing with window and door perimeters that won’t pass inspection and caulk cracking where joints are moving more than expected, we can put it right. A specialist sealant contractor works differently from a general builder: in Maplehurst, that means joint design, primers and backing rod as standard.
Construction in and around smaller places such as Maplehurst is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Construction mastic around Maplehurst: points for this area
At about 35 miles from central London, Maplehurst 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. Maplehurst sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
School extensions, at buildings such as St Andrew's CofE Primary School, normally run to the summer holidays, mastic included. New wings at hospitals like Horsham Hospital, 4.3 miles to the north of Maplehurst, bring long runs of window and panel joints to seal. Units on estates such as Brook Farm Business Park (1.8 miles south-east of Maplehurst) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Maplehurst is about 4 miles south of Horsham, in West Sussex. Across the RH13 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Maplehurst is one of 373 places we cover in West Sussex for mastic packages. Sites around Brighton have their own page, about 14 miles away.

General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
How the job changes by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
Questions we are asked in Maplehurst
Can you take on a job at a hospital such as Horsham Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Maplehurst too small for you to travel to?
Not at all. Maplehurst is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
How long does a job like this take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Will you stick to the specified products?
We follow the specified sealant and flag anything that doesn’t look right for the joint. Specifications often reference BS EN 15651 or BS 6213.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
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: its movement, its surfaces and what it has to cope with.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Why act early in Maplehurst
Refurbishments sometimes budget for new windows when the frames are sound and only the seal has failed. If the frame is in good order, cutting out and resealing the perimeter can be all it needs, which is a much smaller cost. If the frame is life-expired, we’ll tell you. Older rural buildings around Maplehurst 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.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Maplehurst, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
- Work follows the programme, area by area, as rooms and elevations become ready.
- Every joint is prepared, set to depth and sealed with the specified product.
- We close out snagging and hand over with a 12-month guarantee.
Preparing the site
- Have the specification and drawings to hand
- Point out any areas we must not close
- Explain the parking and delivery arrangements
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Use the product the specification names
- Flag uneven or tapered frame gaps early
- Brief the final clean team to avoid blades near sealant
- Don’t schedule sealing before decorators and flooring are done
At handover, keep the product details with the O&M information. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. Tell us what records you need and we’ll confirm with the quote.
Oversized gaps are a problem better caught early. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We raise them during our first walk of the area.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Maplehurst can sit alongside others in a wider programme across West Sussex.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
