Best Detail Sander for Windows: 2025 Expert Review
DR Joinery
Expert Joiner & Restoration Specialist
Stripping and preparing timber windows is perhaps the most tedious job in the trade, but it's also the most critical. If you don't remove the layers of old, flaking gloss and smooth out the timber, your new paint system will fail within a year. In York's Victorian terraces, we often find windows with ten or more layers of paint clogging up the delicate profiles.
Standard orbital sanders are simply too bulky for this work. They can't get into the corners of the frame or navigate the narrow glazing bars without damaging the glass. That is where a quality detail sander (often called a mouse sander) is essential. It allows you to get right into the rebate and tight angles.
In this review, I've selected three detail sanders that I've encountered on site. I have categorised them into a budget option for DIY maintenance, a cordless quality option which is safer for ladder work, and a problem-solving option for specific detailed tasks.

Specs vs. The Real World
The Spec: "Dust Collection Efficiency"
"Manufacturers claim their dust boxes catch almost everything, keeping your workspace clean."
When sanding overhead on a window frame, gravity works against these little boxes. Whilst they help, you absolutely must wear a proper decent mask, especially with pre-1960s paint which may contain lead.
The Spec: "Vibration Reduction"
"Ergonomic grips eliminate vibration fatigue."
If you are sanding a bay window for four hours, your hand will still tingle. The key is to let the sander float on the timber; pressing down too hard increases vibration and creates swirl marks.
My Top 3 Recommendations
Three options to cover different needs and budgets
Detail Sander Electric: DEKOPRO 180W Mouse Sander Corded
DEKOPRO
For homeowners looking to spruce up a single window or door frame, this 180W corded model offers excellent power for the price. It is straightforward, robust enough for softwood frames, and comes with enough paper to get you started.
The Good
- Very affordable price point for occasional use
- 180W motor is surprisingly powerful for stripped wood
- Compact size fits well in sash rebates
The Bad
- Corded design can be awkward when working up a ladder
- Dust collector fills up very quickly on large jobs
Installer Tip:
When using a corded sander on a window, always loop the cable over your shoulder or tap it to the ladder. This prevents the heavy plug from dragging the sander off the work surface, which can gouge the timber.

DEKOPRO
In the trade, going cordless is often a safety necessity rather than just a luxury. This 20V unit eliminates the trip hazard of trailing cables—crucial when you are balancing on a scaffold tower or stepladder tackling a top sash.
The Good
- Cordless freedom makes reaching top sashes much safer
- Dust-sealed switches prolong tool life in dusty environments
- Copper motor runs cooler during extended sanding sessions
The Bad
- Heavier than the corded version due to the battery
- You may need a spare battery for all-day restoration jobs
Installer Tip:
Cordless sanders are brilliant, but they lose RPM as the battery fades. Keep the battery fully charged for the finishing grits (120/180) to ensure you don't leave swirl marks in the grain before painting.

POPULO
This unit offers a higher speed of 14,000 OPM (orbits per minute), making it a problem solver for removing stubborn old varnish or modern water-based gloss that tends to gum up slower machines. The transparent dust box is a simple but effective feature.
The Good
- Higher RPM aids in faster material removal on hardwoods
- Transparent canister lets you see exactly when to empty dust
- Textured rubber grip reduces slipping in sweaty hands
The Bad
- 130W motor has slightly less torque than 180W models
- Corded design limits mobility slightly
Installer Tip:
The high speed is excellent for corners. Use the tip of the triangular pad to get right into the moulding quirk, but be careful not to hold it in one spot too long, or you will sand a flat spot into the profile.
