Custom Garden Trellis in Great Shelford - How to Choose the Right Contractor

What Custom Garden Trellis Can Do for Your Garden

A well-built trellis panel does several things at once. It adds a degree of privacy without solid boarding, lets air move through so climbing plants establish well, and gives your garden a structure that looks considered rather than makeshift. Timber trellis can be sized to sit above an existing fence, frame a garden wall, or stand independently on posts wherever you need height and texture.

Off-the-shelf panels from a garden centre are cut to standard sizes and finished to a standard specification. A custom panel is cut to your exact dimensions, finished in the profile and timber section you choose, and fitted so the fixings and frame suit what it is being mounted to. That difference matters when you have an awkward run, a curved wall, or a design in mind that standard panels simply cannot match.

How to Choose a Contractor - and What to Ask Before You Agree

Choosing a fencing or joinery contractor for a trellis job is straightforward once you know what to ask. The questions below are worth putting to anyone you are considering, including us. A contractor who cannot answer them clearly is one worth thinking twice about.

Ask About the Timber

Not all softwood is the same. Ask what species is being used, what the moisture content is at the time of fitting, and whether it has been pressure-treated. Pressure-treated timber carries a preservative driven into the wood under pressure rather than just brushed on the surface, which matters for any timber in ground contact or in a position where rainwater will sit on it. Untreated or surface-dipped timber will move and split sooner.

Ask about the section sizes too. Trellis battens come in a range of thicknesses. Thinner battens look lighter but flex more and can warp as the timber dries. A 25mm or 38mm batten holds its shape better over several seasons than an 18mm one, especially on a longer span. A contractor who uses whatever is cheapest rather than what the span needs is cutting corners you will notice within a year or two.

Ask About Fixings and Frame

Trellis panels that are fixed directly to a masonry wall without a proper batten frame behind them trap moisture, rot faster, and make it almost impossible to repaint or re-treat the back face. A panel should sit proud of the wall it is mounted to, with a small gap behind it. Ask how the contractor plans to mount the panels and what they are using to fix into the wall or fence. Stainless or galvanised fixings will not rust and stain the timber; bright zinc-plated screws in a damp garden will.

If trellis is going on top of a fence panel or fence post, ask whether the existing posts can carry the extra weight and wind loading. A standard 75mm fence post carrying a 1.8m gravel board panel and a trellis topper is working hard. The contractor should be looking at this, not leaving you to guess.

Ask About Finish and Paint

Trellis can be supplied bare, ready for you to apply your own paint or stain, or it can be pre-primed and painted in a colour of your choice before fitting. Both are valid options. If you want a specific colour, ask whether it is applied before or after installation - painting on site in a fitted position is harder and tends to leave the backs and edges of battens uncovered. Factory or workshop-applied coats before installation get into all the faces and joints properly.

Ask how many coats are being applied and what product is being used. Microporous exterior stains tend to last longer on softwood than solid opaque paints because they let the timber breathe. A good exterior finish on properly prepared, treated timber should give you several years before it needs attention, though the exact lifespan will depend on the exposure of the panel and the finish chosen.

Ask for a Written Breakdown

A price for a trellis job should separate the cost of materials from the cost of labour. This matters because it lets you check what you are being charged for timber and fixings against rough market prices, and it makes any changes easier to price fairly later. A contractor who gives you only a single total figure with no breakdown is making it harder for you to understand what you are paying for.

Ask whether the price includes removing and disposing of any existing panels or structures, and whether it includes making good around fixings if wall drilling is needed. These are the items that often appear as extras once the job is underway if they were not agreed in writing first.

Ask What Happens If Something Goes Wrong

Timber moves. Even well-seasoned and treated softwood will show some movement in the first twelve months as it acclimatises to your garden's conditions. Ask what the contractor's position is if a batten warps significantly or a fixing works loose within a reasonable period. You are not asking for a lifetime promise - you are asking whether the contractor stands behind the quality of the work they have done. A clear, direct answer is a good sign.

What Does Custom Garden Trellis Cost?

For custom-made and fitted timber trellis panels, typical UK prices run from around £80 to £180 per metre run, depending on panel height, batten profile, finish, and what the panels are being fixed to. Simpler square-lattice panels on straightforward fence lines sit toward the lower end. Wider batten spacing, bespoke profiles, shaped tops, or panels that need to be fitted to uneven stonework or brick will come in higher. These figures cover supply and installation; they do not include painting if that is a separate instruction.

It is worth being cautious about quotes that come in significantly below this range. Trellis is not a quick job done properly - the cutting, framing, treating, and fixing all take time, and very low prices usually mean something is being skipped.
