Common questions from Newnham Murren clients
Do you take on work at healthcare sites like Wallingford Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Can you work at a site such as Hithercroft Industrial Estate, by Newnham Murren?
Yes. We cover Newnham Murren and the area around it, including industrial estates, business parks and retail parks such as Hithercroft Industrial Estate. A few photographs and the unit address let us price the work.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Do you replace failed glazing units?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, including perimeters where frames meet the structure.
Can you look at water coming in around a frame?
Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we will set out a timescale with the quote.
Facade sealing in Newnham Murren, done properly
Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. If you have damp patches beside frames after rain and weathered joints at frame-to-structure perimeters, we can put it right, whatever the surface. Looking for mastic applicators who cover Newnham Murren? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
In the countryside around places like Newnham Murren, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Every job we finish is backed by a 12-month workmanship guarantee, in Newnham Murren as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:

- Water getting in through cracked render or porous masonry
- Cracked or spalling substrates that need repair before sealing
If in doubt, phone 01277 525 020 or email a schedule or drawings and we will say what we think.

Facade sealing in Newnham Murren: the local picture
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. Central London is about 44 miles from Newnham Murren. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
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. School extensions, at buildings such as Crowmarsh Gifford Church of England School, typically run to the summer holidays, mastic included.

What we’re called out for in Newnham Murren
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Common reasons buildings call us in:
- Old perimeter mastic that has dried out
- Air leaks through failed facade joints
- Cladding panel joints that have opened up
- Unsightly perimeter sealant on a visible elevation
Units on estates such as Hithercroft Industrial Estate (1 mile west of Newnham Murren) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What to look for in a quote
- Their pre-qualification and accreditations
- Their approach to joint depth and backing
- Proof of insurance
- Whether their applicators hold CSCS cards
Looking after the joints
Once the work is signed off, these steps help:
- Ask about asbestos in pre-2000 mastic
- Clear debris that holds water against joints
- Avoid harsh cleaners on facade sealant
- Note when each elevation was last resealed
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.
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.
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Which sealant the job calls for
- The site’s rules and procedures
- Location, for remote and island sites
- The total length or number of joints
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Where the site is, with the postcode
- Any specification or named product
- Clear photos of the problem areas
- Approximate linear metres or a joint schedule

Why act early in Newnham Murren
Topping up a failed joint usually buys very little time. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. One visit to deal with every failing joint makes more sense than several trips to a place like Newnham Murren, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
What you get with us

- 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.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
