Pilgrims Hatch homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ingatestone Hall (about 4.6 miles north-east) are a reminder that the area around Pilgrims Hatch has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Saint George's church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Larchwood Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic in Pilgrims Hatch
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on tenement windows, brick reveals and timber door frames, and people most often call us about silicone on a period window that looks wrong and cracked mastic round a front door frame.
Around Pilgrims Hatch, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
We stand behind the work with a one-year guarantee.

How the job changes by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside so we finish it carefully.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours per window, depending on the condition of the joints. Parking around Pilgrims Hatch is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Let us know about parking restrictions

Related advice
Leave it or put it right?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Around Pilgrims Hatch, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Why us?
- We leave the area clean and tidy
- Experience in homes, commercial sites and hotels
- Anti-fungal silicone where joints get wet
- 180+ five-star Google reviews

Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Common problems we fix in Pilgrims Hatch
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they generally need raking out.
The most common problems we see are:
- Old cement repairs round a window that have failed
- Mastic that needs renewing before redecorating
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
If you let a flat or house near Brentwood station, older sash windows in a rental need their mastic kept sound to keep the weather out.
