Best Heat Gun for Paint Stripping: 2025 Expert Review

Published 12 December 2025

Stripping paint is arguably the most tedious job in the trade, but it's the foundation of a good finish. In York's older properties, we often encounter windows and doors with ten or more layers of gloss, hiding the beautiful softwood or hardwood details underneath.

Whilst chemical strippers have their place, a decent heat gun is often the most efficient way to lift thick coats of paint. However, choose the wrong one, and you risk scorching the timber, cracking the glass, or burning out the motor halfway through the job.

In this review, I've selected three heat guns that cover different needs: a budget-friendly option for quick DIY tasks, a reliable branded workhorse for larger projects, and a mini precision tool perfect for delicate glazing bars.

Specs vs. The Real World

The Spec: "Temperature Claims (600°C+)"

The Theory

"Higher temperatures strip paint faster."

The Reality

Maximum heat often scorches timber before the paint bubbles properly. For wood restoration, I rarely go above 450°C. Control is far more important than raw heat.

The Spec: "Paint Removal Speed"

The Theory

"The box says it strips paint in seconds."

The Reality

It takes patience. You need to heat the paint just enough to soften the bond without turning it into a gooey mess or releasing dangerous fumes—especially with pre-1970s lead paint.

My Top 3 Recommendations

Three options to cover different needs and budgets

Huepar Tools Heat Gun, Professional Hot Air Gun Kit Dual Temperature

Budget Pick
Huepar Tools Heat Gun, Professional Hot Air Gun Kit Dual Temperature

Huepar Tools

If you just need to strip one windowsill or free up a stuck sash, this Huepar unit offers incredible value. It heats up quickly and includes four nozzles, making it versatile enough for general DIY tasks without breaking the bank.

Price£16.99 (at time of writing)
BrandHuepar Tools
Temp Range400°C / 550°C
Heat Up Time1.5 Seconds
The Good
  • Excellent price point for the features included
  • Includes 4 nozzles (deflector nozzle is essential for windows)
  • Flat-back design allows it to stand upright for cooling
The Bad
  • Build quality feels less robust than trade brands
  • Temperature control is basic (only two settings)
  • Cable could be longer for working at height

Installer Tip:

Use the 'flat-back' feature often. When you pause to scrape, stand the gun upright. This prevents the hot nozzle from burning your bench or carpet and helps the element cool down properly, extending the tool's life.

BLACK+DECKER 1750W Heat Gun, KX1650-GB

Quality Pick
BLACK+DECKER 1750W Heat Gun, KX1650-GB

BLACK+DECKER

Black+Decker is a staple in many toolkits for a reason. This no-nonsense heat gun focuses on reliability over fancy gadgets. The 1750W motor delivers consistent heat without fluctuating, which is crucial when you're working on expensive hardwood joinery.

Price£22.98 (at time of writing)
BrandBLACK+DECKER
Power1750W
Settings460°C and 600°C
The Good
  • Robust motor suitable for longer sessions
  • Consistent airflow and heat maintenance
  • Durable casing can take a few knocks on site
The Bad
  • Lack of variable temperature dial (just a toggle)
  • Does not come with a wide range of accessories/scrapers

Installer Tip:

When stripping sash windows, I favour this gun's steady airflow. However, be careful near the glass. Always use a glass protection shield (or a wide filling knife held against the glass) to deflect heat, otherwise, the thermal shock will crack your detailed Victorian glazing.

Mini Heat Gun, Huepar Tools 500W Hot Air Gun

Problem-solving Pick
Mini Heat Gun, Huepar Tools 500W Hot Air Gun

Huepar Tools

Standard heat guns are often too aggressive for delicate tasks like stripping narrow glazing bars or beading. This mini 500W unit is the perfect problem-solver. It allows for precision heating without risking the surrounding glass or delicate mouldings.

Price£19.99 (at time of writing)
BrandHuepar Tools
SizeCompact / Mini
Max Temp500°C (Concentrated)
The Good
  • Perfect for intricate glazing bars (muntins)
  • Much lighter than a standard gun, reducing wrist fatigue
  • Lower airflow reduces risk of blowing dust onto wet paint nearby
The Bad
  • Not powerful enough for stripping large flat surfaces (doors/frames)
  • Smaller handle might feel odd for those with large hands

Installer Tip:

I keep this in my bag specifically for the corners of sash windows. Standard guns can be clumsy in tight corners, often burning the timber profile. This mini gun lets you soften the paint in the quirk of the moulding without ruining the sharp edges.

Frequently Asked Questions

Heat gun vs Chemical stripper: Which is better for sash windows?
It depends on the complexity. For flat surfaces (stiles and rails), a heat gun is faster and cleaner. For intricate mouldings or if lead paint is suspected, chemical strippers (like poultice systems) are safer and prevent the profile from getting clogged or scorched.
How do I stop the glass from cracking when stripping window paint?
This is the biggest risk. Glass cracks due to thermal shock (heating up unevenly). Always direct the heat gun away from the glass. Ideally, use a glass protection nozzle (shield) or hold a wide steel taping knife against the glass to act as a heat shield. If in doubt, use chemical stripper near the glass.
Is it safe to strip old paint in Victorian houses?
You must be careful. Many York properties built before the 1970s use lead-based paint. Heating lead paint above 400°C can vaporise the lead, which is highly toxic when inhaled. Always wear a high-grade respirator, work in a ventilated area, and keep the heat setting low. If you are unsure, test the paint first.
What tools should I use alongside a heat gun?
A heat gun only softens the paint; you need good scrapers to remove it. Invest in a shave hook (triangular scraper) for mouldings and a stiff putty knife. I also recommend a sharpening stone—a dull scraper makes the job twice as hard and increases the chance of gouging the wood.
Do I need professional help for sash window restoration?
Draft-proofing and full restoration involve more than just paint stripping; they require re-balancing weights, replacing cords, and routing in brush piles. Our team at DR Joinery can handle the full restoration process if the job becomes too overwhelming.
