Construction mastic in Newnham Murren: the local picture
Newnham Murren sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Newnham Murren has a number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
Hospital estates such as Wallingford Community Hospital (to the west of Newnham Murren) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When units on a site such as Hithercroft Industrial Estate, 1 mile to the west of Newnham Murren, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. School extensions, at buildings such as Crowmarsh Gifford Church of England School, usually run to the summer holidays, mastic included.

Leave it or put it right?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. Where an alternative is genuinely suitable, we’ll say so. Around Newnham Murren, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
Pricing mastic packages depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

From enquiry to sign-off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a day or two on a small fit-out and several weeks on a large multi-storey package. Rural sites near Newnham Murren may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

What sealant work can’t fix
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Deciding which fire-stopping product a penetration needs
- Specifying the product where the designer hasn’t
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly.
Joints and surfaces we work on
- Floor and skirting junctions
- Brick and block movement joints
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Sanitary and kitchen joints
After the work
To get the most from the new sealant:
- Use the product the specification names
- Protect sealed areas from following trades
- Note which sealant went where at handover
- Allow flexibility for external sealing in damp or cold weather
Record which products went where in the handover file. Future maintenance is easier when the products are known. We can confirm the handover information you need when we quote.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure, so the installer needs to correct it first. We flag them as soon as we see them.
Questions about Newnham Murren
Is Newnham Murren too small for you to travel to?
Not at all. Newnham Murren is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Hithercroft Industrial Estate, near Newnham Murren?
Yes. Our area takes in Newnham Murren and its surroundings, with estates and business parks such as Hithercroft Industrial Estate included. Photos and a short description are enough for a first look.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
What happens if old sealant might contain asbestos?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
What guarantee comes with a mastic package?
It’s backed by our 12-month guarantee. Protecting sealed areas from following trades helps avoid damage.
Are you insured?

What accreditations do you hold?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
