An awning looks like a small job, yet it’s one of the jobs people most often call someone back to fix. Nearly every time the problem is the joint between the new roof and the existing wall. If that isn’t finished properly, monsoon rain in Krabi finds its way in there before anywhere else.

On the survey Rong checks whether the wall is concrete or lightweight board, the height of the awning against your doors and windows, which way the rain usually blows in, how far it needs to stick out to actually stop driving rain, and where the water will land so it doesn’t splash back onto the wall or across a path.

Typical mistakes are a slope that’s too shallow, so water backs up into the joint; an overhang too short to keep rain off the window; and fixing to a lightweight wall that can’t take the load. If your wall isn’t suitable, Rong will suggest adding posts instead.

We can supply everything, or you can buy the materials and hire the crew only. Send photos of the wall, a wide shot of the house, rough measurements and a location pin on LINE and Rong can give you a first opinion before the site visit.

Designs and options

Wall-mounted awning with brackets

Diagonal brackets under the beams carry the load back to the wall, so there are no posts on the ground. Good for modest overhangs above windows and doors. Not suitable for wide overhangs or lightweight walls, because all the force goes into the wall.

Patio roof or awning with front posts

Can cover a lot more: a terrace, the area in front of the house or a path around it, and the frame is sturdier. The trade-off is posts in the space below, so they need placing where they won’t block a door or walkway.

Lean-to (single-slope) awning

Slopes away from the house in one direction, so water runs straight off the wall. Simple to build and the shape Rong suggests first for most houses, unless the design of the house calls for something else.

Curved awning

Softer look that suits modern houses, but the frame has to be rolled to shape, so it’s more work and more money. If the goal is simply keeping rain out, a straight awning is better value.

Materials: the honest pros and cons

Metal sheet roofing

Near the sea: depends on spec

Pros

  • Affordable
  • Solid, so it blocks the sun well
  • Lightweight

Worth knowing

  • Loud in the rain, not ideal outside a bedroom without insulation
  • Holds heat without insulation

Near the sea, choose a well-coated sheet grade and make sure cut edges and drilling swarf are cleaned up properly.

uPVC (vinyl) roofing sheets

Good near the sea

Pros

  • Doesn’t rust
  • Quiet in the rain
  • Neat appearance

Worth knowing

  • Dearer than metal sheet
  • Purlins must follow the maker’s spacing or the sheets sag

The sheet suits salty air, but the steel frame and brackets still need rust protection.

Polycarbonate

Good near the sea

Pros

  • Lets light through, so rooms stay bright
  • Rust-free and light

Worth knowing

  • Keeps out much less heat than a solid sheet
  • Can go cloudy or yellow with age and needs cleaning now and then

Good over a window where you don’t want to lose daylight. Not a good idea on a wall that takes the full afternoon sun.

Glass on a steel frame

Near the sea: depends on spec

Pros

  • Light, modern look
  • Doesn’t rust

Worth knowing

  • Expensive and heavy, so the frame must be stronger
  • Dust and water marks show clearly and need regular cleaning

Not recommended on a tight budget. If you’re set on a glass awning, send photos of the wall and the area on LINE first so Rong can check it’s realistic.

How the price is worked out

Awning work starts from 10,000 THB, but there is no fixed price. It depends on your site: how far it projects, its length, whether it needs posts, how high the crew has to work, and the price of steel and materials at the time. Rong does a free site survey, then gives you a written itemised quotation. Remote or boat-access locations such as Ko Lanta and Ko Phi Phi carry a travel fee, which is shown in the quotation before you agree to anything.

There is no fixed price. It depends on your site and on steel and material prices at the time. The site survey is free.

Included

  • Free site survey: checking the wall, measuring, and suggesting the right design and material
  • Written itemised quotation
  • Steel frame with rust primer and top coat
  • Roof sheeting and finishing the joint against the house wall
  • Clearing away offcuts and debris when the job is finished

Not included

  • Materials, if you choose a labour-only contract
  • Gutters and downpipes, unless listed in the quotation
  • Repairs to existing wall cracks or damp (a new awning won’t fix a wall that already leaks)
  • Electrical work and lights under the awning, unless listed in the quotation

How a job with us runs

  1. 1

    Send photos on LINE

    Photos plus a location pin. Rong tells you early if the idea is realistic.

  2. 2

    Free site survey

    He checks the walls, the ground and where the rain will go — the things photos can’t show.

  3. 3

    Written, itemised quote

    Full contract (labour + materials) or labour-only. Nothing hidden in a lump sum.

  4. 4

    30% deposit, then work starts

    Only once you have agreed the design and price. Payment is by cash bill, no VAT invoice.

  5. 5

    Walk-through before handover

    We check every point with you. 1-year warranty under the conditions in the quote.

How long it takes

It depends on the length, how many awnings, working height and the weather. Sealing against the wall should be done when the wall is dry, so a run of rainy days can mean waiting. Rong gives a timeline after the survey and it goes in the quote.

1-year warranty: what it covers

One year, under the site-specific conditions written into your quotation.

Covered

  • Installation workmanship by our crew
  • 1-year warranty, under the site-specific conditions written in your quotation

Not covered

  • Damage from unusually severe weather or natural disasters
  • Anything the quotation does not list as covered by the warranty

Awnings & Lean-to Roofs: questions we get asked

Will the awning leak where it meets the wall?

That joint really is where most awnings leak. The usual causes are too shallow a slope, no flashing (the folded strip that covers the joint), or relying on silicone alone, which breaks down in sun and rain. Rong sets the slope to carry water away from the wall and finishes the joint properly. When you compare quotes, ask every builder how they finish that joint.

How far should an awning stick out to stop the rain?

There’s no single number. The higher the awning is mounted, the further it has to project to keep driving rain off, and the wind direction matters too. Rong judges it on site and will tell you honestly if the overhang you can have still won’t stop all slanting rain.

What’s the difference between an awning and a carport?

An awning projects a modest distance from the wall to keep sun and rain off the house. A carport has to cover enough ground to park a car, so it usually needs posts and a heavier frame. If you might park under it one day, say so at the start rather than extending an awning later.

Which roofing is quietest over a bedroom window?

uPVC sheets or foam-backed metal sheet are clearly quieter than plain metal sheet in a downpour, though they cost more. For a window that isn’t a bedroom, plain sheet is usually fine, and Rong can price both options in the quotation.

I’m renting. Can I still have an awning put up?

Yes, as long as you have written approval from your landlord, since it’s fixed to their building. If the house is in a managed village or condo, check the juristic-person rules as well. We can talk the landlord or property manager through the plan at the site survey.

How does payment work? Do you give a tax invoice?

We take a 30% deposit before work starts, and the balance is paid as set out in the quotation. You get a cash bill, but we do not issue VAT or tax invoices. If your company or landlord needs a tax invoice, tell us at the start so there are no surprises.
