If automation is even a possibility later, it changes the gate now: heavier hinges, a cable duct under the drive, and posts sized for a motor. Cheaper to allow for it on a Welwyn Garden City install than to retrofit. Welwyn Garden City sits inside our core patch — AL7 and the surrounding Herts area. On metal gates, that means we've already seen how the original garden city movement housing — neo-georgian semis and short terraces with consistent frontages behaves over a service life, and we spec accordingly.

Galvanised steel or wrought-iron-style frames with hardwood or composite infill. Standard build: 50×50mm SHS frame, 40×40mm infill or hardwood slats, hot-dip galv + RAL powder-coat. On Welwyn Garden City jobs we adjust for welwyn garden city has design covenants — front fences typically restricted in height and style.
Property mix locally: the original Garden City Movement housing — neo-Georgian semis and short terraces with consistent frontages. Typical gardens: rear gardens hidden behind tall established hedgerows; many properties sit on the original 1920s grid. Postcodes we regularly service: AL7, AL8.
We'll say so on the site visit — a wasted quote helps nobody.
Galvanise then powder-coat: the coat is cosmetic, the galvanising is what keeps a Welwyn Garden City gate off the rust list. We allow for rear gardens hidden behind tall established hedgerows; many properties sit on the original 1920s grid when setting out in Welwyn Garden City. Worth weighing won't warp, drop or shrink the way timber does against impact damage usually means welding and re-coating on site before you commit.
Galvanise then powder-coat: the coat is cosmetic, the galvanising is what keeps a Welwyn Garden City gate off the rust list. Survey slots across AL7 are usually inside a week. Practically, that means handles automation loads without the reinforcement carpentry timber gates need — and we're upfront that no natural warmth — often paired with timber slats or composite infill.

Worth weighing won't warp, drop or shrink the way timber does against impact damage usually means welding and re-coating on site before you commit.
Hinge posts are set deeper and concreted wider than fence posts because a steel leaf loads them every single day. For the original garden city movement housing — neo-georgian semis and short terraces with consistent frontages in AL7, that is where the cost sits. Worth weighing won't warp, drop or shrink the way timber does against impact damage usually means welding and re-coating on site before you commit.
Swing direction and drive fall decide whether a Welwyn Garden City pair swings in, out or slides — surveyed first, not assumed. We allow for rear gardens hidden behind tall established hedgerows; many properties sit on the original 1920s grid when setting out in Welwyn Garden City. Practically, that means handles automation loads without the reinforcement carpentry timber gates need — and we're upfront that no natural warmth — often paired with timber slats or composite infill.
Checking hinge screws are still tight and that the gate still closes flush against the frame once or twice a year catches the early stages of sag before it becomes a full repair job.
A gate that's starting to catch on the ground is far cheaper to fix at that stage than after the frame has racked further out of square.
Care home boundaries need to manage two directions of risk at once: keeping the site secure from outside, and, where residents live with dementia, preventing unsupervised exit through a garden gate that looks like a normal feature of the grounds.
Gates onto care home gardens are often specified with a delayed-release or coded latch rather than a simple thumb-turn, agreed with the home's management against its own care regulator requirements.
Access for contractors on an occupied care site usually needs coordinating around resident routines and quiet hours rather than a standard domestic working day.
Structural and treated timber is typically stamped with a grading mark showing the strength class, treatment use class, and sometimes the treatment company's code, which is the practical way to verify what was actually supplied rather than taking a description on trust.
For fencing, the marks that matter most day to day are the use class (confirming it's rated for the ground or above-ground exposure intended) and a visible batch or treatment date, useful if a defect needs tracing back to a supplier.
Unmarked or unstamped 'treated' timber from an unclear source is harder to verify and is one of the more common shortcuts on cut-price quotes.
Joist spacing under a deck is set by the board being used and the load expected, not fixed universally — timber boards typically need joists at closer centres than the equivalent composite board, because composite is generally less stiff across a span.
Manufacturers publish maximum joist spacing for their composite boards, and it's shorter still where boards run diagonally rather than square to the joists, since a diagonal run effectively increases the unsupported span between fixings.
Undersized joist spacing shows up as bounce or long-term sag between joists well before it becomes a safety issue, so it's worth checking spacing against the actual board spec rather than a generic rule of thumb.
Where a fence line crosses from a garden onto a patio, driveway or other hardstanding, post bases usually need core-drilling into the existing slab rather than a dug hole, which is a different technique and a different price than fencing over soil.
A change in level along a run — a step up to a raised patio, or a drop to a lower side passage — needs the fence height measured consistently from the ground it's actually protecting, not from an average across the whole run.
Getting this detail wrong is one of the more common reasons a finished fence ends up looking uneven even though every panel was fitted correctly on its own section.
A slide bolt needs its guide staples and keep perfectly in line along the bolt's travel, since even a slight misalignment makes the bolt bind partway rather than sliding freely, which is often mistaken for a stiff or rusted bolt.
Re-aligning the staples after a gate has settled or a post has moved usually resolves this without needing to replace the bolt hardware itself.
A drop bolt on the leading edge of one leaf of a double gate needs a matching socket set into the ground or a fixed plate below it, and that socket has to be positioned after the gates are hung and checked closed, not marked out in advance from a plan.
Ground movement or a slight settling of the gate posts over the following months can throw the bolt out of alignment with its socket, which is why some installers set the socket in a slightly oversized recess rather than a tight-fitting hole.
Where the ground under the gate is loose gravel or soft earth, a concrete socket set flush with the surface holds alignment far better over time than a bolt simply pushed into bare ground.
It's not unusual for a drainage manhole cover to sit directly on, or very close to, a garden boundary line, reflecting how shared drainage runs were originally laid out.
Water companies and building control generally expect ongoing access to manhole covers to be maintained, which can rule out building a fixed fence panel or post directly over one.
Where a boundary run includes a manhole cover, planning a removable panel section or routing the fence slightly around it avoids blocking access that may later be needed for drain clearance.
Where a registered public right of way crosses land that's being fenced, it's not something that can simply be blocked — a formal diversion order from the council is needed to legally move its route.
This process typically involves public consultation and can take a meaningful amount of time, so it needs building into any project timeline where it's relevant.
Checking the definitive map of public rights of way, held by the county or unitary council, before finalising a fence layout avoids inadvertently obstructing a protected path.
Widening a single gate opening into a double-leaf gate usually needs a new or repositioned hanging post partway across the opening as well as a slamming post on each outer side, rather than simply hanging two narrower leaves off the existing posts.
This is more involved than a straightforward repair and is worth planning against the full opening width before committing to a leaf size.
Where an electric vehicle charge point is fitted near a boundary, cable routing sometimes needs to cross under or through a gate or fence gap, which is worth considering at the design stage rather than retrofitting a channel later.
Trailing a charging cable across a public footway to reach a car isn't permitted in most areas without specific council-approved cable channel provision, which is a separate matter from the fence itself.
Checking the council's position on any cable crossing a footway, alongside the fence and gate design, avoids two separate problems being discovered one after the other.
Pressure treatment doesn't necessarily saturate a timber section all the way through, and the depth of genuine preservative penetration, sometimes called the treatment envelope, can be shallower in dense or resistant species than the treated colour suggests.
Cutting a treated post in half reveals this directly, often showing a pale, untreated core surrounded by a darker treated outer band a few millimetres to a couple of centimetres deep depending on species and process.
This is the practical reason cut ends need separate end-grain treatment, since a fresh cut through the envelope exposes untreated core timber that the original pressure treatment never reached.
The Party Wall etc. Act 1996 covers work to a shared wall or excavation near a neighbour's foundations, and while an ordinary timber fence on a boundary line usually falls outside it, a new masonry boundary wall built astride the line, or deep post holes close to a neighbour's foundations, can bring it into play.
Where the Act applies, formal written notice is required before work starts, giving the neighbour a defined period to consent or dissent, and proceeding without notice risks an injunction even on otherwise straightforward work.
Even where the Act doesn't strictly apply, a simple letter or conversation confirming line, height and access before work starts avoids most of the disputes that end up needing formal resolution.
Lichen tends to establish on horizontal or gently sloped timber surfaces that stay damp longest, which makes flat-topped capping and post caps more susceptible than the vertical panel faces below them.
Unlike algae, lichen grows slowly and bonds tightly to the timber surface, so a stiff brush rather than a pressure washer is usually needed to remove it without damaging the wood fibres underneath.
Once removed, a capping profile with a fall to shed water reduces how quickly lichen re-establishes compared with a flat top that holds a film of moisture after every rain.
We fabricate to the opening rather than cutting a stock gate down, so the gap at the meeting stiles is even top to bottom across AL7, AL8.
