Why it matters
Beam tops are flat shelves that gather dust, insects and cobwebs, which drift down when doors open or the HVAC runs.
Rustic and timber-frame restaurants, breweries and venues rely on beams as a design feature, and cobwebs ruin the look.
Grease-laden dust on beams near cooking areas is harder to remove the longer it sits.
How AELC providers clean beams and rafters
Every AELC Network Provider follows the AELC Source-Control Method: do not move the contamination; capture it or contain it. For beams and rafters, that means:
- Identify. Measure beam lengths, note heights, finishes and grease, and choose the reach class.
- Protect. Cover tables and equipment beneath the work.
- Capture. Vacuum beam tops with a HEPA source-capture vacuum and beam-top tool on a high-reach pole.
- Contain. Damp-wipe sides and bottoms with finish-safe methods.
- Verify. Check tops from a lift or mezzanine where available, and photograph.
Typical reach class: Standard to Elevated Access. About AELC reach classes.
How often should beams and rafters be cleaned?
| Setting | Recommended frequency |
|---|---|
| Restaurants and breweries | Every 3 to 6 months |
| Churches and venues | Every 6 to 12 months |
| Warehouses | Every 12 months |
Grease, lint, humidity and how visible the area is can shorten these intervals. See how often high dusting should be done.
How much does beam and rafter cleaning cost?
Typical range: $1.00–$3.00 per linear foot (per linear foot of beam). Large timbers, grease and lift work raise the price.
Prices are set by each independent provider. Ranges reflect published market data and AELC time standards. See the full above-eye-level cleaning cost guide.
DIY vs. hiring a pro
- Never climb onto beams or use unsecured ladders to reach them.
Safety and when to stop
- Lift work is Elevated Access with a trained operator.
- Stop if dust may contain hazardous material or if there is evidence of pests or droppings in large quantities.

Industries that need it
Beam and Rafter Cleaning: frequently asked questions
How do you clean the tops of high beams?
With HEPA source-capture vacuums on high-reach poles fitted with tools shaped for beam tops, so dust is pulled in rather than pushed off. Very high beams use a lift.
How is beam cleaning priced?
Usually per linear foot, adjusted for beam size, height and grease.
