FNO Services Europe
Drupal Maintenance Services for Businesses
Practical technical support for established Drupal websites
FNO Services Europe provides Drupal maintenance services for businesses that need an experienced technical partner to keep an existing Drupal website secure, stable and maintainable.
We can help with Drupal core and contributed-module updates, Composer dependencies, Drush, database updates, configuration management, hosting issues, custom modules, integrations and problems introduced by changes to PHP or the server environment.
Support is available for websites originally built by another developer or agency. We begin by reviewing the current installation, access, codebase, hosting and update status before recommending changes.
What is included in Drupal maintenance services?
Drupal website maintenance involves more than clicking an update button. Modern Drupal websites commonly depend on Composer packages, contributed modules, custom code, database updates, configuration files and server-level settings working together.
The appropriate maintenance process depends on how the website was built and how important it is to daily business operations.
Drupal core updates
- Drupal patch and security updates
- Composer dependency updates
- Database update checks
- Release-note and compatibility review
- Post-update functional checks
Module and theme maintenance
- Contributed-module updates
- Theme compatibility checks
- Deprecated module review
- Dependency-conflict investigation
- Replacement planning where projects are unsupported
Composer and Drush support
- Composer installation and update problems
- composer.json and composer.lock review
- Drush command troubleshooting
- Scaffold and dependency issues

- API and data-feed integrations
- Incremental feature improvements
Drupal core, module and Composer updates
A Composer-managed Drupal installation should normally be updated through its project files and lock file rather than by replacing files manually.
A responsible update process may include:
- Reviewing available Drupal security and maintenance releases
- Checking the installed PHP and database versions
- Creating or confirming a recent backup
- Reviewing Composer dependency constraints
- Checking contributed-module compatibility
- Applying code and dependency updates
- Running required Drupal database updates
- Rebuilding caches
- Checking administrative and public-facing pages
- Recording important technical changes
We do not recommend applying every update blindly. A website with custom modules, patches, integrations or an older theme may need additional review before dependencies are changed.
Drupal security maintenance
Drupal has a structured security-release process, but installing a security update safely still requires an understanding of the individual website.
Security-related Drupal maintenance can include:
- Reviewing relevant Drupal core and contributed-project advisories
- Applying supported security releases
- Checking whether abandoned modules remain installed
- Reviewing administrator accounts and permissions
- Checking configuration and private-file exposure
- Reviewing unusual errors, changes or access patterns
- Updating PHP or dependencies where compatibility permits
- Confirming that backups are stored appropriately
Routine maintenance is not the same as continuous security monitoring or a guaranteed incident-response service. Any required monitoring, malware investigation or emergency response must be agreed separately.
Drupal website maintenance for sites built by another agency
You do not need to be the original development client. We regularly work with established websites where the original agency, freelancer or internal developer is no longer available.
Before taking responsibility for maintenance, we normally establish:
- Who controls the domain, DNS and hosting
- Whether server, SSH and Drupal administrator access is available
- Where the Composer project and source code are stored
- Whether the codebase matches the live website
- How backups are created and retained
- Whether configuration management is in use
- Which modules and themes are custom
- Whether patches or manual code changes have been applied
- Which integrations and scheduled processes are active
- Which updates or defects require immediate attention
When access, ownership or technical history is unclear, start with our Website Takeover Check.
Drupal configuration and deployment support
Drupal configuration can be stored in the database and exported to configuration files for controlled deployment between environments.
We can help investigate problems involving:
- Missing or incorrect configuration-sync directories
- Configuration import and export failures
- Environment-specific settings
- Development, staging and production differences
- Configuration that exists only in the live database
- Modules enabled in code but missing from configuration
- Deployment processes that overwrite or lose changes
- Database updates that were not completed after deployment
The appropriate workflow depends on whether the website is managed through Git, Composer, a hosting deployment system or direct server access.
Support for custom Drupal modules and integrations
Some Drupal websites include custom modules or integrations that are essential to their business operation. These may connect Drupal to marketplaces, CRMs, payment providers, product feeds, internal databases or reporting tools.
We can review existing custom functionality to understand:
- What business process it supports
- Which Drupal services and APIs it uses
- Whether deprecated code needs to be replaced
- How it stores or exchanges data
- Which credentials and external services it depends on
- Whether failures are logged clearly
- How it is affected by Drupal or PHP updates
Substantial custom-code work may be treated as application maintenance. See our application maintenance and support services.
For a new external connection, see our API integration services.
Drupal performance and hosting troubleshooting
Slow Drupal performance is not always caused by Drupal itself. The underlying issue may involve hosting resources, database queries, caching, external services, modules or server configuration.
Performance investigation may include:
- Drupal cache configuration
- Database size and slow queries
- Views and content-query behaviour
- PHP memory and execution limits
- Web-server and compression configuration
- Large files or image-processing workloads
- Scheduled tasks and cron
- External API requests
- Errors repeatedly written to logs
- Hosting limitations or unsuitable architecture
When a move is justified, our website migration services cover Drupal code, databases, Composer dependencies, private files, configuration and server requirements.
Drupal upgrades and legacy-version support
An older Drupal installation may require more than routine maintenance. Unsupported core versions and abandoned modules can make normal hosting, PHP and security updates increasingly difficult.
A legacy Drupal review can identify:
- The installed Drupal core version
- Supported and unsupported contributed modules
- Custom modules and themes
- PHP and database compatibility
- Available upgrade paths
- Content and configuration migration requirements
- Functionality that needs replacement or redevelopment
- Hosting constraints and deployment risks
A major-version upgrade is normally a separate project rather than routine monthly maintenance. We will explain whether incremental preparation, migration or redevelopment is the most practical option.
Our Drupal maintenance process
1. Initial discussion
Tell us what the website does, which Drupal version it uses and which maintenance or technical problems need attention.
2. Access and technical review
We review the available Drupal, hosting, SSH, Composer, database and source-code access.
3. Priority assessment
Security issues, failed updates and operational problems are separated from routine work and longer-term improvements.
4. Backup and preparation
Appropriate backups and safeguards are confirmed before significant changes are applied.
5. Controlled maintenance
Updates and fixes are performed using a process appropriate to the website and its hosting environment.
6. Verification and documentation
Important functions are checked and significant findings, changes and recommendations are recorded.
Drupal maintenance pricing
The appropriate plan depends on the complexity of the Drupal installation, the amount of custom code and the level of ongoing responsibility required.
Website Care — £39 per month
May suit a small and stable Drupal website requiring light routine attention, subject to an initial technical review.
Support Bank — £120 per month
Reserved support time for updates, troubleshooting, Composer work, hosting issues and ongoing Drupal tasks.
Growth Support — £220 per month
More regular technical capacity for active Drupal websites, custom functionality and continuing improvements.
Ad-hoc support — from £35 per hour
Available for defined one-off tasks where an ongoing maintenance arrangement is not required.
Complex debugging, major Drupal upgrades, emergency recovery and high-risk custom-code work are assessed separately. Agency or developer escalation normally starts from £55 per hour with a minimum project value of £150.

Frequently asked questions
Can you maintain a Drupal website built by another agency?
Yes. We first review the available access, codebase, Composer project, modules, hosting and current update status.
Do you support Composer-managed Drupal websites?
Yes. We can work with Composer dependencies, lock files, Drupal scaffolding and command-line update workflows.
Can you fix a failed Drupal update?
Potentially. We will need to review the error, current files, database state, backups and the update steps already attempted.
Can you maintain custom Drupal modules?
Yes, after reviewing the code, purpose, dependencies and compatibility requirements.
Can you upgrade an older Drupal website?
We can assess the available upgrade path. A major-version upgrade is usually scoped separately from routine maintenance.
Can you migrate Drupal to another server?
Yes. We can review the codebase, Composer dependencies, database, file directories, configuration and hosting requirements.
