If you are using a child theme, you might want to try the following code (located in header.php).
<div class="header-inner section-inner">
<div>
<?php
$custom_logo_id = get_theme_mod( 'custom_logo' );
$legacy_logo_url = get_theme_mod( 'baskerville_logo' );
$blog_title_elem = ( ( is_front_page() || is_home() ) && ! is_page() ) ? 'h1' : 'div';
$blog_title_class = $custom_logo_id ? 'blog-logo' : 'blog-title';
$blog_title = get_bloginfo( 'title' );
$blog_description = get_bloginfo( 'description' );
if ( $custom_logo_id || $legacy_logo_url ) :
$custom_logo_url = $custom_logo_id ? wp_get_attachment_image_url( $custom_logo_id, 'full' ) : $legacy_logo_url;
?>
<a class="logo" href="<?php echo esc_url( home_url( '/' ) ); ?>" rel="home" style="float:left; clear:both;" >
<img src="<?php echo esc_url( $custom_logo_url ); ?>">
<span class="screen-reader-text"><?php echo $blog_title; ?></span>
</a>
<?php endif; ?>
<h1 class="blog-title">
<a href="<?php echo esc_url( home_url() ); ?>" rel="home"><?php echo $blog_title; ?></a>
</h1>
<?php if ( $blog_description ) : ?>
<h3 class="blog-description"><?php echo $blog_description; ?></h3>
<?php endif; ?>
</div>
</div><!-- .header-inner -->
