The Brief
A Tired Opening, Properly Put Right
This is the kind of external frame and threshold project we take on regularly across Berkshire: an opening that has quietly let the homeowner down for years — a draught around the edges in winter, a sill that holds water rather than shedding it, timber gone soft at the foot of the jamb. The door itself may still close well enough, but the frame it sits in has reached the point where a repair would simply be delaying the inevitable.
The grace of this kind of work lies in the precision it demands rather than anything showy. A new frame is only as good as the opening it sits in and the care taken to set it square, plumb and properly packed — get any of that wrong and the most expensive timber and the finest threshold in the world will still let water and draughts back in within a season or two.
Done properly, the result is an opening that behaves exactly as it should: a door that closes with a satisfying, even resistance, a threshold that turns away rain rather than collecting it, and a frame that will happily see out several decades before it needs attention again.

The Process
From Worn-Out Frame to Weathertight Opening
Removal comes first, and it is done with more care than it might appear to need — the old frame is eased out of the brick opening rather than wrenched free, protecting the surrounding reveals, render and brickwork from unnecessary damage. With the opening bare, it is checked thoroughly for level, square and any hidden damp or decay in the surrounding brick or lintel before a new frame is ever offered up, since a beautiful new frame fitted into a compromised opening is no fix at all.
The new frame is then offered into the opening and packed with timber shims exactly where the gap between frame and brick calls for it, checked for plumb on both faces with a spirit level at several points before a single fixing is driven home. Getting this stage right is what separates a frame that will perform for decades from one that will start binding, sticking or letting in draughts within a year or two — it is unhurried, deliberate work, and it is where the real craft of the job lives.
With the frame fixed square and solid, a weathertight threshold and weatherbar are fitted across the base of the opening, set to shed water away from the house rather than let it pool or track back underneath. Sealant is then worked carefully into every frame-to-brick joint, chosen and applied to move with the building rather than crack and fail within a season, before the door itself is hung and the whole opening is tested — opened, closed, and checked against draughts — as part of finishing the job.

Specification
Materials & Approach
- Timber specified for exterior joinery and treated for continuous outdoor exposure before it reaches the opening
- A weathertight threshold with weatherbar, set and sealed to shed water away from the house rather than collect it
- Frames fixed and packed to the brick opening with shims and fixings sized to the structure, not a one-size-fits-all approach
- A flexible, weather-grade sealant worked into every frame-to-brick joint to keep the opening watertight and draught-free
- A weather-resistant finish applied once the frame is fitted, matched to the rest of the property's joinery where required
- No shortcuts on packing or sealing — a frame that looks fitted but is not properly weathered is not how we approach this work
Common Questions
Door Frame & Threshold Fitting — Frequently Asked Questions
How do I know if my door frame needs full replacement rather than a repair?
It comes down to how much sound timber is left. If the decay or damage is confined to one section — the sill or the foot of a jamb, for example — a splice repair can often put it right. Where the rot has spread through the frame, the timber has twisted out of square, or draughts and water ingress are a persistent problem, a full replacement is the more honest and longer-lasting answer. A free site visit tells you which category you are in before any money is spent.
How long does an external door frame and threshold swap take?
A straightforward single-door frame and threshold replacement is typically a one-day job from removing the old frame to the new one being fixed, packed and sealed, with the door itself hung once the sealant has cured. Where the brick opening needs remedial work, or render needs to be made good around the reveals, we allow extra time and confirm it upfront in the quote.
Is my house secure while the old frame is out and the new one is being fitted?
Yes. We plan the work so the opening is never left open and unattended — the old frame is only removed once the new one is ready to go in, and the door is temporarily secured at the end of each working day until it is fully hung and operational. Security is discussed and agreed as part of the quote, not an afterthought.
Will the new frame match the existing brick reveals and render?
Wherever possible, yes. We work carefully around the existing brick reveals and, where render or pointing is disturbed during the fit, we make it good to match the surrounding finish rather than leaving an obvious scar. Timber profile and finish are also matched to the rest of the property unless a different look has specifically been asked for.
What causes an external door frame to fail in the first place?
Nearly always a combination of standing water and time. A threshold or sill that sheds water poorly, a gap in the sealant at the frame-to-brick joint, or simply decades of weather on untreated or under-maintained timber will eventually let moisture into the joints, and rot follows from there. A well-detailed, well-sealed new frame and threshold is built specifically to avoid repeating the same failure.
What timber and treatment do you use for an external frame?
We use timber specified for exterior joinery and treated appropriately for continuous outdoor exposure before it ever reaches the opening, with a weather-resistant finish applied once fitted. The exact specification depends on the door style and the property, and is confirmed in writing as part of the quote.
Do you fit the threshold and weatherbar as standard, or is that extra?
A weathertight threshold and weatherbar are a core part of any external frame fit, not an optional extra — fitting a new frame without properly detailing the threshold would simply reintroduce the water-ingress problem the work is meant to solve. It is priced into the job from the outset.
Do you offer any guarantee on door frame and threshold work?
All our external frame and threshold work is covered by our standard workmanship guarantee, details of which are confirmed in writing with your quote. If a seal or joint were ever to fail under normal use, we would come back and put it right.
