How to Update a 1970s Brick Fireplace: Modern DIY Makeover

Shirley Jun 01, 2026

Updating a 1970s brick fireplace is one of the most rewarding home improvement projects you can undertake. Often serving as the stubborn focal point of a basement or living room, these fireplaces are a relic of an era when aesthetics favored avocado green and harvest gold. While the structure itself is built to last, the visual appeal may feel outdated or clash with a modern interior design. By following a systematic approach, you can transform a dated eyesore into a contemporary anchor that adds warmth and value to your home without sacrificing the character that brick inherently provides.

Assessing the Existing Structure

Before selecting new materials or grabbing a paintbrush, you must evaluate the physical condition of the fireplace. A 1970s build might conceal structural issues that could compromise safety if ignored. Start by checking the integrity of the bricks and mortar; look for signs of spalling, cracking, or excessive efflorescence, which indicates moisture problems behind the surface. Next, verify that the damper functions correctly and that the flue is clear of obstructions. If you are unsure about the safety, hiring a certified chimney sweep for an inspection is the prudent first step to ensure your update plan addresses the actual condition of the system rather than just the cosmetic finish.

Understanding Modern Efficiency Standards

One of the primary motivations for a 1970s fireplace update is to improve energy efficiency. Traditional brick fireplaces are notorious for drawing warm air up the chimney, creating a negative draft that sucks heated air from the living space. To combat this, you have two main paths: installing a tight-sealing glass door or opting for a modern insert. Glass doors significantly reduce the influx of cold air when the fire is not burning, while inserts are engineered to burn wood much more efficiently, often exceeding 70% efficiency compared to the 10% of an open hearth. This upgrade not only saves on heating bills but also makes the room comfortable to use regardless of the fire’s status.

Design Strategies for a Modern Look

Once the structural and functional checks are complete, the design phase allows you to define the fireplace’s new personality. The goal is to bridge the gap between the old brick and the new aesthetic. You do not have to cover the entire surface; sometimes, framing the existing brick with a modern material creates a stunning contrast. Alternatively, you might choose to embrace the vintage element and paint the surrounding brick a bold, matte color to make it recede into the background, allowing the focus to remain on the fire itself. The key is to align the finish with the overall palette of the room, ensuring the update feels intentional rather than accidental.

Material Selection and Application

When deciding on the materials to apply over the 1970s brick, you will typically choose between paint and tile. High-heat paint is a cost-effective and transformative solution, available in finishes ranging from sleek matte to sophisticated velvet. This method is ideal if you want to maintain the texture of the brick but eliminate the "dirty" look. For a more dramatic and durable surface, heat-resistant tile can be applied to the firebox or the surrounding hearth. Thinset mortar and proper sealing are critical to ensure the tile withstands the intense heat and daily use. Remember to select materials specifically rated for high temperatures to avoid peeling or cracking over time.

Refreshing the Surrounds

The area immediately surrounding the fireplace often holds the biggest visual impact. The hearth, mantle, and surrounding walls act as the frame for the brick, so updating these elements can modernize the entire feature instantly. Replacing a tired wooden mantle with a slab of concrete, quartz, or even reclaimed wood can completely change the character of the space. If the surrounding walls are covered with dated drywall or paneling, covering them with large-format peel-and-stick wallpaper, shiplap, or plaster will create a seamless transition between the old brick and the new design. This step effectively turns the fireplace from a forgotten relic into a curated statement piece.

Accessorizing for the 21st Century

Finally, the accessories are what breathe new life into the updated surface. The metalwork of the fireplace—tongs, poker, and shovel—can be swapped to match a modern brushed nickel or matte black finish to replace the often-gaudy brass of the 70s. The mantel is the perfect spot for a minimalist sculpture or a curated collection of objects that reflect your personal style rather than the trends of a bygone decade. Additionally, consider the lighting; replacing a dated pendant with a sleek, modern fixture directly above the mantel will enhance the ambiance and highlight the texture of the updated brick. These finishing touches ensure the fireplace looks as good as it functions.
