Construction mastic for Forge Wood sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Why deal with it now?
Leaving mastic to whichever trade is fitting the element can look cheaper on paper. In practice it often means different standards, gaps in responsibility and snags nobody owns. One mastic subcontractor for the lot keeps it simple. Small buildings around Forge Wood suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

How we handle construction mastic in Forge Wood
The specification and the programme set the job. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Joint widths, backing, primers and tooling follow the manufacturer’s guidance, so the joints perform as the designer intended. If you’re dealing with window and door perimeters that won’t pass inspection and different trades sealing to different standards, we can put it right. A single leaking joint is often how a building in Forge Wood first comes to us: we look at the rest while we are there and tell you what we find.
Building work in places the size of Forge Wood is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Our process

Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes. For a job in Forge Wood, the main thing is a clear picture of the work. You will then get a fixed price for the work.
- First we look at the scope on site or from drawings.
- You receive a fixed quote covering scope, products and sequence.
- Site paperwork is confirmed and our CSCS-carded applicators are inducted.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised right away.
- Final snagging is completed and the 12-month guarantee applies.

How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Whether the work must be split into stages
- Quantities, in metres or numbers
- Distance, for remote addresses
- Removal of failed or old sealant
Pricing mastic packages depends on quantities, condition and access. Ask us for a fixed quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Any dates the work must fit around
- How the joints are reached, and at what height
- The postcode of the building
- What the building is and how it’s used
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Questions about Forge Wood
Could you schedule work at a campus like Crawley College for the vacation?
Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Forge Wood Industrial Estate, near Forge Wood, within your area?
Yes. We cover Forge Wood and the area around it, including industrial estates, business parks and retail parks such as Forge Wood Industrial Estate. A few photographs and the unit address let us price the work.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.
What accreditations do you hold?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we will confirm with the quote.
Can you seal external joints in wet or cold weather?
External mastic depends on conditions: the joint needs to be dry and within the product’s temperature range. We plan external elevations with that in mind.
Contractors’ notes for Forge Wood
Forge Wood 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 the external programme keeps a little slack. A 2-mile radius around Forge Wood takes in plenty of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
For a contractor working at a hospital such as Langley Green Hospital (psychiatric), which lies west of Forge Wood, perimeter and facade sealing is planned around patients and deliveries. For a contractor at a hotel such as Sandman Signature London Gatwick Hotel, 1 mile to the south-west of Forge Wood, the mastic often has to be finished before a reopening date.

When to call us in Forge Wood
Value-engineered products sometimes end up in the wrong joints. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
Most enquiries start with something like this:
- Caulk cracking where joints are moving more than expected
- Old sealant on a refurbishment that needs stripping before new work
- Window and door perimeters that won’t pass inspection
- New external sealant already peeling away
When a school such as Forge Wood Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
